Issue: No data from GPS doing a cat /dev/ttyAMA0, no time reference in packet forwarder
Setup: I have a RAK2287 bundle, with the shield with a GPS on it (it is a MAX-7Q instead of advertised ZOE-M8Q GPS chip). I use the software I received on the microSD with the bundle.
Server: configured with TTN following the tutorial, but currently it won’t mark gateway as connected… even if the packet forwarder sends data and doesn’t give any error. => I fixed it by removing the temp variable from being sent in the JSON to TTN, as this is not an allowed variable and leads to rejection of the STAT info. Now it is good, except the GPS…
Thanks for the answer on this point Nick. As I said in the edited post, in my situation that was caused by a “temp” variable in the STAT packets sent to TTN, that was not accepted by TTN. I fixed it the packet forwarder, recompiled it, and that now works properly. But that’s useful to know, as I already experienced something similar as what you describe with my other gateway.
Still, no data from the GPS on my gateway, that part of the problem remains.
Hi Nicholas, I put it in a place where my neo-6M based other GPS is working properly, with the same antenna. However, even if I had no coverage, I should have data flowing from GPS don’t you think?
Is that also expected that GPS chip is a max-7Q for an European customer, when a ZOE-M8Q is advertised everywhere from the webshop to the docs?
I also have RAK2287, I found the Zoe-M8Q is actually on the rear of the minipcie card, its antenna connector is also on the minipcie card, adjacent to the lora rf connector. This Zoe-M8Q provides the 1pps sync for the SX1302 and its serial output is on ttyAMA0. Once it has a lock, you can see a 1pps flash from blue LED under the RF shield.
The other GPS module on the adaptor HAT is not connected to 1pps of the SX1302.
