GNSS override is ignored for waveshare_sx1302_lorawan_gateway_hat #184

Closed errolt closed 3 weeks ago

errolt commented 1 month ago

What happened?

Setting model_flags=[ "GNSS" ] is ignored when model="waveshare_sx1302_lorawan_gateway_hat"

What did you expect?

I expected the GPS to be used. If I set model="rak_2287", with the waveshare radio still connected, then the GPS is used, even though the GPS on the module isn't UBLOX

Steps to reproduce this issue

Steps: Add GNSS for model_flags, set model to waveshare_sx1302_lorawan_gateway_hat and set log_level="DEBUG"

Could you share your log output?

With model="waveshare_sx1302_lorawan_gateway_hat"

Side note. This is running on a Radxa Rock 5B board. Hence the strange GPS port, i2c port and GPIO allocations.

If this is an issue proving that the GPS on the waveshare hat works fine, even though it isn't Ublox, then I'll be happy to set up a PI4 to do the same tests.

brocaar commented 1 month ago

The Waveshare shield does not have an U-blox GNSS module. Please note that the Semtech HAL only supports the U-blox GNSS modules because it relies on a proprietary binary message for accurate time syncing.

errolt commented 1 month ago

@brocaar Did you read my complete report? The GPS module on the waveshare hat WORKS if I tell concentratord that I have a rak_2287. Does changing the model in the config magically change the GPS module to a UBLOX module?

As I noted in another issue a few years ago, the waveshare GNSS module has been modified to emit UBLOX time messages.

So in the end I just have to run my concentrator misconfigured, set up as a rak_2287, with incorrect power calibration or whatever that causes, just to get GPS to work?

brocaar commented 3 weeks ago

I have tested with my Waveshare module to reproduce what you are saying, but it does not work for me. The Waveshare module only reports NMEA RMC messages. If it supports the NAV-TIMEGPS (which is a proprietary u-blox msg), it should have printed this in the logs every second and it does not:

https://github.com/chirpstack/chirpstack-concentratord/blob/master/chirpstack-concentratord-sx1302/src/handler/gps.rs#L98

This is what the Concentratord outputs:

Tested with a custom Concentratord that enables GPS for the Waveshare module.

I can not find a single source that confirms that the GNSS module should support this: https://www.google.com/search?q=quelctel+l76+%22NAV-TIMEGPS%22

Sample output for my gps: gps_sample.txt

Note that I got that output with:

Just to be sure, I tried with your config but I can not reproduce the same output with NAV-TIMEGPS using your config.

Maybe your shield is from a different batch, that I don't know. However to support GPS I would like to see a confirmation from Waveshare that this is expected to work. Mine has a Quectel L76 module and I can find zero references that this module is supposed to support the NAV-TIMEGPS binary messages.

See below the picture of my shield + GNSS module:

I have not looked at my older hat, but the new hat on my desk has a Q76K, which might have the ublox addition? 20241028_155734

errolt commented 3 weeks ago

So, as some hats does not emit Ublox messages, GPS can't be enabled for all waveshare hats, but it should be optionally enablable?

brocaar commented 3 weeks ago

What we know is that the Waveshare module & hat comes with a GNSS module which is officially not supported by the Semtech HAL (which is used by the Concentratord) and that it seems to work in your case (because the GNSS module has a different firmware?), but not in all cases (it does not work in my case). As well I can not find any resource published by Waveshare or Quectel why it is supposed to work in some cases. I would rather not provide features based on assumptions.

Therefore I think it is better to officially not support it.

Since your shield seems to be different from mine, you could make the following config and recompile the Concentratord:
