Hi there. I have a very strange problem using my Electron board when plugged into the breadboard. When I run my Electron board standalone (not plugged into the breadboard) then it handshakes with the server and sends message absolutely fine. If I plug it into the breadboard it is not able to contact the server (can’t get to the internet or can’t handshake), i.e. lots of cyan flashes and then two or more red flashes. If I then unplug it from the breadboard it works fine.
Nothing else is plugged into the breadboard.
I have the battery connected in all cases.
I am using the SIM that came in the package with the Electron board, it is inserted correctly and my data limit has not been reached.
I’ve peeled the back off the breadboard and buzzed-out all the tracks to confirm that no adjacent tracks (side by side or across the central divide) are connected to each other.
Signal strength here is good (-69 dBm as measured by the board itself). I have a video of this behaviour, if anyone wants to see proof, but it is a 20 Mbyte file.
Wassup!? Stray capacitance perhaps?
