[07:31] <SA6BSS-Mike> ok
[07:32] <SA6BSS-Mike> well, a 10uf cap on the aprs board seems to have fixed restart issue, now its getting close to test this new setup :)
[07:32] <SA6BSS-Mike> now Im of to work for 4 h
[07:33] <OZ1SKY_Brian> Have a good one Mike, 4H is bearable :-)
[07:34] <SA6BSS-Mike> tnx, yeah, it quite ok
[07:36] <SA6BSS-Mike> here is the git with fw and pcb ifyou or anyone is interested https://github.com/micked99/SX1278
[07:36] <OZ1SKY_Brian> wow thats small and good looking
[07:42] <VK5QI> that chip will do 4FSK just fine too ;-)
[07:45] <OZ1SKY_Brian> and we do love our 4FSK :-)
[07:46] <VK5QI> im working on an updated release of horus-gui and associated stuff at the moment
[07:46] <VK5QI> which adds support for the v2 mode, which is a bit more customizable
[07:46] <OZ1SKY_Brian> cool, looking forward to it.
[07:50] <OZ1SKY_Brian> we got 2 new trackers here now, but dont know them, just that they are on the map

[07:51] <VK5QI> uhh
[07:51] <VK5QI> yeah 4 RTLSDRs on one machine is asking for trouble
[07:51] <OZ1SKY_Brian> as soon as sdr4 kicks in, it crashes
[07:52] <OZ1SKY_Brian> also with a powered usb hub
[07:52] <VK5QI> i think this is just a RTLSDR thing
[07:53] <VK5QI> there is some stuff in the works to use a multi-channel SDR backend btw, i had a long zoom call with Phil Karn the other day
[07:53] <VK5QI> who is developing such a thing.
[07:53] <VK5QI> well, *has* developed it, but it needs some changes to be useful to auto_rx
[07:53] <PE2BZ> GM all, 434.662 is the right QRG for the RTTY tracker indeed

[10:35] <VK5QI> yes there is 200 baud in the list for RTTY now
[10:35] <PE2BZ> Now downloading :-)
[10:37] <VK5QI> there is also support for decoding Horus Binary v2 payloads, though you are unlikely to see any of that in the wild for a while
[10:38] <VK5QI> the v2 packet format is more to allow for custom data fields, which i expect more to be used in other payloads
[10:38] <VK5QI> i have a lot of documentation to write before that happens

[11:07] <PE2BZ> VK5QI, that´s not a big problem. I live at 52 N and 4.2 E :-)
[11:08] <PE2BZ> Save me a lot of typing.
[11:08] <VK5QI> haha
[11:10] <PE2BZ> Mark, I am not 100 pecent convinced of the rtty decoding at 200 baud. The signal is not very strong, but so far no decodes on the horus gui. I will try again in half an hour and make a recording from the Icom reception
[11:11] <PE2BZ> The SNR goes from -10 (noise) to around -1 when the transmission starts
[11:12] <PE2BZ> but ¨decode failed. could not parse rtty sencence -crc failed¨ where dlfldigi gives a green decode.
[11:14] <VK5QI> that could just be from the transmitted string
[11:14] <VK5QI> got an example of a complete string?
[11:16] <PE2BZ> $$$$$BZ-RTTY-5,182,11:13:22,53.68833,.87336,7550,"0,60,7*1,3.72,3.63*F678
[11:16] <PE2BZ> From dlfldigi decoded
[11:16] <VK5QI> uh
[11:17] <VK5QI> thats a corrupt sentence i guess
[11:17] <VK5QI> because i see a * in the middle of the sentence
[11:17] <PE2BZ> let me retry that ;-)
[11:17] <PE2BZ> $$BZ-RTTY-5,184,11:16:08,53.67360,1.88066,7527,19,70,9.6,3.62,3.54*72FE
[11:17] <VK5QI> looks OK :/
[11:18] <PC4L> how do I use 200bd @horus gui, I only see 100 and 300 bd?
[11:18] <PE2BZ> https://rfhead.net/horus/horusgui/
[11:19] <PE2BZ> Just update :-)
[11:19] <PC4L> Am I using 0.8 :))
[11:20] <PE2BZ> The version with 200 baud support has at least been online for over an hour ;-)
[11:20] <VK5QI> PE2BZ: well the sentence structure looks ok
[11:20] <VK5QI> a recording (with a reasonable signal) would probably help
[11:20] <VK5QI> have you successfuly received a signal from this payload at a different baud rate?
[11:21] <VK5QI> as changing the baud rate doesnt really affect any of the downstream RTTY frame extraction stuff
[11:21] <PE2BZ> Not with horus gui, no,
[11:21] <PE2BZ> But I´ll await PC4l
[11:22] <PC4L> s t a r t i n g
[11:22] <VK5QI> PE2BZ: so it might be some other issue with the telemetry...
[11:22] <PE2BZ> PC4l´s results
[11:23] <PE2BZ> Strange thing, last 3 strings give 0 dB SNR, mask estimation works, I see mark and space in the spectra window, but
[11:24] <PE2BZ> latest packet raw gives just a lot of garbage.
[11:24] <PE2BZ> which I can copy with right mouse button, but cannot paste ?
[11:25] <PC4L> $$BZ-RTTY-5,190,11:24:24,53.62933,1.91191,7536,18,70,p\pXf\lnXf\jrTh
[11:25] <PC4L> almost :)
[11:25] <PE2BZ> But the tracker is returning home so the signal should improve
[11:25] <PE2BZ> PC4L, can you copy and paste that from the horus gui ?
[11:26] <VK5QI> its possible that its not happy with the modulation
[11:26] <VK5QI> like, if there's any gaps between transmitted bytes it will not lock on well
[11:27] <VK5QI> unlike dl-fldigi, horusdemodlib does not treat rtty transmissions on a byte-by-byte basis - it looks for a header ('$$$$$') and then looks for the '*XXXX' CRC
[11:27] <VK5QI> can you link the code that is producing this?
[11:27] <PC4L> there´s the first decode using horus
[11:28] <PC4L> https://ibb.co/b112zTd

[11:30] <VK5QI> a wav file would be nice
[11:30] <PE2BZ> This was a movie file from the screen recorder.
[11:30] <VK5QI> though im mor einterested in the code thats doing this transmission
[11:30] <PE2BZ> rr https://github.com/RoelKroes/TBTracker
[11:31] <PE2BZ> But at PC4L it decodes great :-)
[11:31] <PE2BZ> So I am checking my settings.

[11:32] <VK5QI> ok its radiolib, so its probably delay-based RTTY transmission
[11:35] <VK5QI> yeah i thin kpart of the issue here may be to do with short gaps between byts
[11:35] <VK5QI> bytes*
[11:36] <VK5QI> the horus FSK demod expects a continuous bitstream, not one where some bits are a bit longer than others :-)

[12:27] <vincentsan> SA6BSS-Mike, thks ! I'll try now! For those interested, here are some pictures: https://s3.eu-west-1.amazonaws.com/www.up-in-the-air.com/Up4-2sides.jpg and https://s3.eu-west-1.amazonaws.com/www.up-in-the-air.com/Up4-weight.jpg
[12:35] <vincentsan> SA6BSS-Mike, does not work either... I still get ~40mA average consumption. Do you send another command before? I've tried as first command and also after disabling NMEA without luck.
[12:41] <SA6BSS-Mike> you have to stop the serial or it will be powered through the rx/tx pinms
[12:42] <vincentsan> ok, let me investigate that on mbed...
[12:43] <vincentsan> Your command seems to disable GNSS only. What current did you get after that?
[12:45] <SA6BSS-Mike> hang on , I need to eat first back in 10

[12:48] <vincentsan> Running your command after initializing the GPS reduces the consumption down to 6.63mA. This seems in line with https://ukhas.org.uk/guides:ublox_psm#:~:text=Switch%20the%20RF%20GPS%20section%20off%2C%20draws%20about%205mA%2C%20retains%20its%20settings%2C%20wakes%20on%20serial%20command.
[12:49] <vincentsan> But it seems to only stop the GNSS and not put the GPS in full backup mode (should be less than 1mA).
[12:50] <vincentsan> I'll try to investigate if the problem comes from the serial

[12:59] Nick change: SA6BSS-Mike1 -> SA6BSS-Mike
[13:08] <SA6BSS-Mike> I would say the Serial draw might only acure if you turn the gps off by cutting its VCC and not by doing it by sw
[13:08] <SA6BSS-Mike> so the serial likley not the cause for the 6.1mA
[13:08] <vincentsan> ok
[13:09] <vincentsan> 6.1mA does not seems odd since it only stops the GNSS
[13:09] <vincentsan> but I don't understand how to switch it off completely through software
[13:10] <SA6BSS-Mike> but the max 6 says about 5mA , it never gets below that
[13:10] <SA6BSS-Mike> so if you get 6.1 on max7 its about the same
[13:11] <vincentsan> you mean I can not activate the backup mode through software (15uA for MAX7Q and 300uA for MAX7C) ?
[13:11] <SA6BSS-Mike> as you runinng it on solar 3-4mA wont change anything regarding up time and solar wake up
[13:12] <SA6BSS-Mike> I have tried bu not found the setting, I simply had the option of turning the GPS completely off by cutting VCC so I never dough any deeper into the mather
[13:13] <vincentsan> you're right, but I do need to add a supercap because I can not (yet) control TX power with Lora E5 and it draws 45mA.
[13:13] <vincentsan> so I am tight on max current draw
[13:13] <vincentsan> and since I do have to use a supercap, I wanted to try to continue emit at night everything else than position
[13:14] <vincentsan> this will be possible only if I can completely switch off the GPS
[13:14] <SA6BSS-Mike> ok, but 45mA with 6psc 39x19 should be good to below 20° solar with cells only
[13:14] <SA6BSS-Mike> aha, ok
[13:15] <vincentsan> well, the peak will be closer to 55mA with GPS (GNSS switch off)
[13:16] <vincentsan> And i'd like something: I think with lora I can get a rougth position just with TDOA, even at night
[13:16] <SA6BSS-Mike> yes, only aprs tx "keep alive" with no aprs is fine
[13:16] <SA6BSS-Mike> *with no gps
[13:16] <vincentsan> yes, but for that I need to switch off this gps...
[13:17] <SA6BSS-Mike> tried ublox center?
[13:17] <vincentsan> nope
[13:17] <vincentsan> new lead, thks
[13:17] <SA6BSS-Mike> that would be you next step
[13:18] <vincentsan> yes, that's strange though that nobody reports on this problem and I'm seen a lot of people reporting completely switching off the GPS by software.
[13:18] <LeoBodnar> I turn GPS on/off via a extintBackup pin
[13:20] <LeoBodnar> SW works too
[13:20] <vincentsan> can you share your UBX command?
[13:20] <LeoBodnar> for SW?
[13:20] <vincentsan> yes, please
[13:20] <vincentsan> maybe it does not work for MAX7Q
[13:21] <vincentsan> EXTINT would be an option but it would require some fine tip soldering ;-)
[13:21] <SA6BSS-Mike> LeoBodnar: does pin5 pull low turn off the MAX modules?
[13:22] <vincentsan> let me try. i think EXTINT backup is not configured by default, is it?
[13:23] <SA6BSS-Mike> ok, so its apin you can set to a nr of thing, thats what I remeber from reading up a few month ago
[13:24] <LeoBodnar> idk, I use bare M8030 and you can set whatever GPIO you want for extintBackup
[13:25] <LeoBodnar> I have used b5 62 02 41 8 0 0 0 0 0 2 0 0 0 on MAX-7
[13:29] <vincentsan> LeoBodnar, it looks like the same command as given by SA6BSS-Mike. It does switch off GNSS but no the entire module and I still have a curent of 6.6mA.
[13:30] <LeoBodnar> 6.6mA is too high for backup and too low for continuous
[13:30] <LeoBodnar> is it periodic PSM?
[13:31] <vincentsan> no Continuous Mode
[13:31] <LeoBodnar> 6mA in continuous? wow
[13:31] <vincentsan> with GNSS off it makes sense
[13:31] <LeoBodnar> then it's not continuous mode :D
[13:32] <vincentsan> but from my understanding GNNS off != backup mode
[13:32] <LeoBodnar> GNSS as a task or as a HW?
[13:33] <LeoBodnar> there is a GNSS task in Ublox module
[13:34] <LeoBodnar> GNSS task can be running or stopped. When it is stopped the rest is all ticking along - comms, etc
[13:34] <LeoBodnar> in backup the whole core is off and to do anything you need to wake it up first
[13:34] <vincentsan> I turn on the module, disable NMEA, configure NAV_MODE, configure continous mode, then stop GNSS with your UBX command and I get 6.6mA
[13:35] <PE2BZ> vincentsan, I received 2 developer board adn one chip indeed, I have been able to TX with the AT commando´s, but I am (more as a bit !) clueless how to proceed writing a program for it. So if you have any testing firmware available ? I think I managed to get the programming software running :-)
[13:35] <LeoBodnar> oh that makes sense
[13:35] <vincentsan> yes, I think I am in your first case: "GNSS is stopped and the rest is all ticking along - comms, etc"
[13:36] <LeoBodnar> putting module into backups state does not stop GNSS task afaik
[13:36] <vincentsan> but whenever I try other backup command: {0xB5, 0x62, 0x06, 0x57, 0x08, 0x00, 0x01, 0x00, 0x00, 0x00, 0x50, 0x4B, 0x43, 0x42, 0x86, 0x46}, nothing happens
[13:37] <vincentsan> so you are saying I should first stop GNSS task, and then put module in back up ?
[13:37] <LeoBodnar> no, you would not want to stop GNSS task unless you have a good reason to
[13:37] <vincentsan> survive night with a supercap
[13:37] <LeoBodnar> it's taken care of by the RTOS
[13:38] <LeoBodnar> just going to BACKUP state is all you need
[13:38] <vincentsan> yes, but the module does not respond to that and continues to draw ~40mA
[13:38] <LeoBodnar> there is no point trying it on HW until you have it working through Ucenter
[13:38] <vincentsan> ok
[13:39] <vincentsan> sounds sane
[13:39] <LeoBodnar> it should be really a fallback for any problem with commands
[13:39] <vincentsan> does it work on mac os ? ;-)
[13:40] <LeoBodnar> under VMWare it does
[13:40] <vincentsan> does not seem to...
[13:40] <vincentsan> ok, will need more time then !
[13:40] <SpacenearUS> New vehicle on the map: 03W3UAV-15 - 12https://tracker.habhub.org/#!qm=All&q=W3UAV-15
[13:41] <LeoBodnar> are you using UART or I2C?
[13:41] <LeoBodnar> I use I2C on the tracker and UART for Ucenter
[13:41] <vincentsan> UART
[13:42] <LeoBodnar> ah ok
[13:42] <vincentsan> but I can try with a spare chip
[13:42] <vincentsan> do you know if MAX7C and MAX7Q behave the same, software wise?
[13:43] <LeoBodnar> yeah get it ALL working in Ucenter and then transfer to the HW
[13:43] <vincentsan> Ok, will make it work with MAX7C and then transfer on HW with MAX7Q
[13:44] <vincentsan> PE2BZ, it has been a long road but I managed to program the Lora E5 mini and my custom board. Starting with the seeedstudio pointers and finally moving the mbed which is great!
[13:44] <LeoBodnar> I think 7C has slightly higher backup current since it does not have a 32K crystal so it uses its 26MHz crystal in backup state
[13:44] <vincentsan> ok, but should be the same software wise
[13:44] <LeoBodnar> 7Q turns TCXO off and uses 32K fork crystal
[13:44] <LeoBodnar> yeah
[13:45] <vincentsan> I can't help myself to first try with EXTINT ;-)
[13:46] <LeoBodnar> 7C can go lower in Vdd
[13:46] <SpacenearUS> New vehicle on the map: 03KB1KVR - 12https://tracker.habhub.org/#!qm=All&q=KB1KVR
[13:46] <vincentsan> yep, no problem, at night no GPS but only TX
[13:48] <vincentsan> PE2BZ, biggest pitfails are: 1/ configure the radio switch 2/ configure the PA to not draw more than 45mA at 14dB. In fact, the module is not very well optimized for 14dB
[13:48] <vincentsan> in terms of power / consumption
[13:50] <LeoBodnar> if you really need minimum current you can use limitPeakCurr in UBX-CFG-PM2
[13:50] <LeoBodnar> it works in both PSM and continuous mode
[13:50] <vincentsan> Do you think that can be a substitute for back up mode?
[13:50] <LeoBodnar> saves you about 2-3mA
[13:50] <LeoBodnar> no!
[13:50] <vincentsan> ok
[13:51] <LeoBodnar> but if you are near the limit it mihgt help
[13:51] <vincentsan> Ok, I don't think I am really current limited at day. Only at night during which i don't need the GPS so only need a way to switch it off
[13:52] <LeoBodnar> nothing comes close to backup mode short of cutting the power
[13:52] <LeoBodnar> backup mode should be about 200-300uA
[13:53] <LeoBodnar> cutting the power is not a good solution because initial startup current is higher than when you come out of backup
[13:53] <vincentsan> ok, I don't feel so bad about removing this MOFSET I had in the design at first ;-)

[13:54] <vincentsan> I will try EXTINT and software control with Ublox center. I'll report here when it works!
[13:58] <vincentsan> PE2BZ, let me know it you need some help with the Lora E5. I can drive you through the step I took.
