hi @viniaero.
First you have to check that you see the sky Pls check with command “sudo cat /dev/ttyAMA0” that you have NMEA stream. If you have , try to stop the ttn-gateway.service with “sudo systemctl stop ttn-gateway” and then start the start.sh script (sudo ./start.sh) inside /opt/ttn-gateway/packet_forwarder/lora_pkt_fwd .
Let me know how is going.
Regards
Sorry i have missed the cat command ! (edited)
The command is with no spaces in the path “sudo cat /dev/ttyAMA0”
And you should see something like this :
If not check the settings in the raspi-config.
Regards
Ok. Next thing . Pls go to raspi-config , 5 Interfacing Options, 6 Serial , answer No to Login Shell and Yes to Serial port to be enabled. Reboot and test again. If this does not work pls check that in /boot/config.txt has lines - enable_uart=1 , dtoverlay=pi3-disable-bt , core_freq=250
Hi @viniaero . I am sorry that we cannot help with this so far.
Please check the u.fl connector of the GPS antenna for some problems, both on the antenna and board.
Mine looks as the picture in the manual.
Yours appears to be reversed indeed.
I did not realize you meant the GPS module, but thought the whole board was the issue.
This would indeed make sense, as we were not able to fix your GPS issues. Not surprisingly if the module is soldered in reverse
From what I can find on the Ublox website the pin direction is directly related to the sticker so there is not chance just the sticker is reversed. Thus I am 99% sure that it is reversed, plus the actual GPS issues. I advice you contact RAK for a replacement. @Fomi, @kenyu, @kinsonchan could you please chime in and assist us here. Perhaps I am mistaken and we can solve the issues in a less time consuming way ?
It seems that your RAK2245 is an I2C interface GPS hardware. It is an old version of RAK2245 which has been discontinued, and all of RAK2245 Pi HAT is UART interface GPS now.
So i think you can contact with @kenyu ([email protected]) for exchanging an UART version RAK2245.
