Description

I'm using DIY NRF5280 ProMicro with TCXO. The GPS Module is a HGLRC M100 5883 (I am sure it's working because from ucenter 2 I can connect and send/receive commands); this module is basically a M10050-KB with onboard antenna and compass (unused). I tried all 2.5 Meshtastic versions from 2.5.7.f77c87d (I couldn't compile 2.4 on this board because it gives out errors). Pins are correct since I can see messages being transferred to/from device by sniffing data with a FTDI Serial adapter (I also tried swapping them with no success).

I wonder why it tries all gps devices apart from Ublox ones? DEBUG | ??:??:?? 85 [GPS] Trying $PDTINFO (UC6580)... DEBUG | ??:??:?? 85 [GPS] Trying $PDTINFO (UM600)...

The output would be too long, it just probes on all baudrate for each gps type and after some minutes it gives up.

Hi, thanks for the report.

The ublox-relevant message is:

No response for class 06 message 08 .

As you're familiar with making firnware, could you place

define GPS_DEBUG 1

In your variant.h and upload detailed logs?

macvenez commented 5 days ago

That's the output with GPS_DEBUG already enabled, now I'm trying on an ESP32 to check whether it makes any difference

fifieldt commented 5 days ago

with GPS_DEBUG enabled, the GPS will output anything it receives over the serial line ... since there's nothing at all in the logs, most likely means the wrong pins are being used somehow , or GPS_DEBUG was not enabled

macvenez commented 5 days ago

I'll try that again later, maybe that's because I did #define GPS_DEBUG instead of #define GPS_DEBUG 1? Thanks

fifieldt commented 4 days ago

I had a quick check of the code and it looks like just defining GPS_DEBUG would work :(

macvenez commented 4 days ago

I tried on an ESP32 running Meshtastic 2.5.8 and it works, there must be something wrong with pinouts or maybe the hardware serial on the NRF52.

That's the only output I got from the GPS on NRF52 (I couldn't get the whole log but that was probing on 9600):

The GPS seems to be answering something (I rebooted the device many times and I would say I'm getting some output like 1 time out of 10). There must be something wrong on serial receive on NRF52 as on ESP32 it works flawlessly... I'm using a Nrf52 promini (the ones from aliexpress) with a sx1262 if that may help...

fifieldt commented 3 days ago

Left field thought - are you specifying pins in the app or in variant.h? Pin handling from the app is different between esp and nrf

macvenez commented 3 days ago

I am specifying them from variant.h Btw I am receiving something so wiring must be ok. I'll try also from the app then, if it makes any difference. What could be the issue with software? Could it be something related to bootloader or softdevice version?

macvenez commented 3 days ago

I tried older bootloader with no result.

By tying together RX and TX pins on the NRF52 I can see what it spits out:

I can see the attempt at 9600 is quite different... (that's also the frequency the ESP32 device correctly connects to the GPS at)

Is this a desirable output?

macvenez commented 2 days ago

Yeah, excellent. So looks like the GPS is hooked up correctly but not responding to the Ublox "are you a Ublox" command in the way we expect.

I think the next step is to decode B562060800000E30 and work out what that is according to the Ublox specification.

Wait, that was the messages when RX and TX on NRF52 side were tier together so it was basically echoing itself (I was trying to understand whether it was working). That B562060800000E30 is sent by the nrf52 The real issue is the NRF52 doesn't get all messages the GPS module sends. At this point this must be something clock related because same meshtastic version works with an ESP32 configured the same way. The GPS module is wired correctly as sometimes some messages are received by NRF52 and sometimes not like here:

As we can see here just 2 messages are sent by the GPS module and the GNRMC is the default polling for NMEA data. I also tried setting the GPS module (from ucenter through a ftdi adapter) at 4800 baud and I couldn't receive anything when wiring it back to the nrf52(in case the serial clock was very imprecise on the NRF52)
