Has anyone else had a problem using GSM/GPRS on this board simultaneously with the raspberry pi onboard Ethernet?
For me, the Ethernet loses connectivity for a few seconds whenever data is transmitted.
I have tried using the PPP tutorial on the product page and communicating directly with the M95 module using AT commands via UART.
Both methods are successful at transmitting data to a server, but the Ethernet issue is present with both methods.
It is only resolved when the tracker HAT is powered from a second raspberry pi which is leading me to think its a power issue.
