Since the board is prepared to solder a SMA plug I’d suggest doing that for our gateways:
The SMA connector costs about 0,20€, it can be done very quickly and the SMA connector is much better and stable than the u.fl. What do you think?
Hi…these messages are ‘normal’ due to SPI timing issues with the RPi3. If you wait for a few minutes the gateway should start. However, as Borroz correctly observed, you need to update the configuration (create an applicable local_conf.json) as your current configuration does not point to TTN.
