[18:15] <ly2en> https://pasteboard.co/Y4UGlh2GKKNW.jpg <- simple 46mm gps wire. still no luck, just some sporadic fixes. tried like 6 different wires, lengths, tested on two gps units (atgm336h)
[18:17] <SA6BSS-Mike> and if you put your phone next tot the board and open the app: GPS Test it finds lots of sats?
[18:18] <ly2en> i put it under a clear sky - into the balcony
[18:18] <SA6BSS-Mike> facing south?
[18:18] <SA6BSS-Mike> it should not really mather but...
[18:19] <ly2en> I've bought an apartment for myself on a condition that my working room will be facing south
[18:19] <SA6BSS-Mike> I get gps lock on the north but not as good as on the souty side of the house
[18:19] <ly2en> so, yes :)
[18:19] <SA6BSS-Mike> great
[18:20] <ly2en> I'm starting to think I've got a bad shipment of gps units
[18:20] <SA6BSS-Mike> so thats "my " pcb ?
[18:20] <ly2en> yeah I think this one has been widened to 20x20mm
[18:20] <SA6BSS-Mike> ok
[18:20] <ly2en> so that I could have the pcb assembly at the jlcpcb
[18:21] <SA6BSS-Mike> pic of the other side?
[18:21] <ly2en> because they don't do smaller than 20x20 and yours was 19x20 or something
[18:21] <ly2en> now it's in the box but I will get a pic of another one
[18:23] <ly2en> https://pasteboard.co/IUlEEHSNYAx0.jpg <-usb hub with two rs232 adapters to monitor gps rx and tx and also an usbasp
[18:23] <ly2en> so I can program it "remotely" and debug both ends
[18:24] <SA6BSS-Mike> so , if you put it on 2AA bat and takes it out to the street , no change
[18:24] <SA6BSS-Mike> ?
[18:24] <ly2en> last one that worked is ready for a flight in a dark waterproof box
[18:25] <ly2en> I will take one 18650 battery and take it out
[18:25] <ly2en> tomorrow maybe
[18:25] <ly2en> or when the kid goes to sleep
[18:25] <SA6BSS-Mike> ok, hope thats not fully charged
[18:25] <SA6BSS-Mike> 4,2V is to much
[18:25] <ly2en> well it is something 3.7
[18:25] <SA6BSS-Mike> thats better :)
[18:25] <ly2en> i have a few of those anyway
[18:25] <ly2en> and 5v didn't kill it in hours
[18:26] <ly2en> ttps://pasteboard.co/hjQqMRa4cuqE.jpg <- front view of the remaining one
[18:26] <SA6BSS-Mike> have you deoldered the same pcb and just fitted another GPS module, or have you built 2 boards?
[18:26] <SA6BSS-Mike> *desoldered
[18:27] <ly2en> I have 2 boards, one is QFN, the other is this TQFP
[18:27] <SA6BSS-Mike> ok
[18:28] <SA6BSS-Mike> no risk of solder bridhes on that ic
[18:28] <SA6BSS-Mike> looking good
[18:28] <SA6BSS-Mike> and the ICT fw from my git?
[18:28] <ly2en> is there a thing like atgm336h firmware or something?
[18:28] <SA6BSS-Mike> nothong
[18:28] <SA6BSS-Mike> used them for years without problem
[18:29] <ly2en> SA6BSS-Mike: the GPS code is not touched from your git, I have modified the code a bit in the txtiming part
[18:29] <ly2en> added CW beacon and some more
[18:29] <SA6BSS-Mike> same code worked on the other board?
[18:29] <ly2en> yep I have one working board
[18:29] <ly2en> :)
[18:29] <ly2en> it's untouchable, locked now in safe place
[18:30] <SA6BSS-Mike> it tx all fine the oscillator test?
[18:30] <ly2en> damn maybe it's the CW beacon, I will turn it off now just for the sake of it
[18:30] <ly2en> I've added it to see if the si5351 works, just like an oscillator
[18:30] <SA6BSS-Mike> the gps need about 40sec to have time to lock in
[18:31] <ly2en> it was out in the balcony for 2+ hours
[18:31] <ly2en> actually I've again burnt two days trying to figure out
[18:31] <ly2en> like, resolder stuff, go out with the kid to play, return in 1hour - no fix
[18:32] <SA6BSS-Mike> does the cw beacon keep tx with no lock?
[18:32] <ly2en> no, it does it only in setup()

[18:33] YO9GJX (~YO9GJX@109.100.112.132) left irc: Remote host closed the connection
[18:34] <ly2en> nothing fancy at this point, will rewrite it to beep(*char[])
[18:34] <SA6BSS-Mike> but if you load the original fw to the board with the 2 min timing , does that work?
[18:35] <ly2en> haven't tried that yet, took my own as a baseline
[18:35] YO9GJX (~YO9GJX@109.100.112.132) joined #highaltitude.
[18:38] <ly2en> running your code for 2 mins now, no fix yet
[18:40] <SA6BSS-Mike> wait till the kid/s sleep and put it outside without the plastic box
[18:41] <ly2en> it's actually outside the plastic box now
[18:41] <ly2en> just few cms
[18:42] <SA6BSS-Mike> some plastic boxes are good in keepimg the high freq gps out
[18:42] <ly2en> and with clock divideed by 4 the rx/tx behaves weirdly on the GPS pins - might be related ?
[18:42] <SA6BSS-Mike> runing at 2 is not a "clean" bouddot freq
[18:42] <ly2en> to actually read the 9600 I had to comment out the division so now running on 8
[18:43] <ly2en> both pins read normally @8
[18:43] <SA6BSS-Mike> yes, the fw even runs fine at 1Mhz
[18:43] <SA6BSS-Mike> but it much happier at 8
[18:43] <ly2en> PCAS04 set to 1 i see on TX
[18:43] <SA6BSS-Mike> andmore snappy
[18:43] <ly2en> and the RX gets the no-fix flood
[18:43] <ly2en> the ",,,,,,,,"
[18:45] <SA6BSS-Mike> and if you put your phone out in the plastic box it gets a good gps fix?
[18:46] <ly2en> I get a t-beam gps fix on my desk inside :( with an internal antenna
[18:47] <ly2en> will share few more pics, gotta go for a lullaby
[18:48] <SA6BSS-Mike> those antennas on those boards are acrive and really quite good
[18:48] <SA6BSS-Mike> rr
[18:48] <ly2en> she wants 5 more minutes with mom, so I have 5 more mins with hab
[18:49] <SA6BSS-Mike> :)
[18:49] <ly2en> https://pasteboard.co/cA1JvNsO3o47.jpg
[19:06] <ly2en> what if I will just desolder the gps, power it on, attach the antenna and see if it works independently

[19:15] <ly2en> seems like a hardware glitch, maybe a poor ground or something
[19:15] <ly2en> need to change the testing conditions :(

[20:02] <ly2en> running independently on 3.1V now, but still nothing
[20:02] <ly2en> maybe I will become wiser in the morning
[20:14] <Prutz> Was thinking... did anyone tried to make a buoy ? Just drop it in the sea and see where it goes
[20:26] <ly2en> yes there was a buoy
[20:27] <ly2en> somebody mentioned that on groups.io few months ago
[20:27] <bertrik> how do you get the telemetry from the buoy to a receiver? you don't have the advantage of line-of-sight
[20:29] <bertrik> so you use "HF" then for greater range? but you will also need a lot more power I think
[20:29] <bertrik> or maybe satellite, but probably very expensive
[20:48] <Prutz> Only thing would be LoRa I think
[20:49] <Prutz> Line of sight on open water should go furter
