OK, so I bought by mistake a Plasma 2350 without W. No problem, I though, I’ll get an RM2 and connect using the SP/CE cable, there’s sample code. Did that, tried to run the example. Thonny shows me an ‘invalid pin’ error in this line:
wlan = network.WLAN(network.STA_IF, pin_on=32, pin_out=35, pin_in=35, pin_wake=35, pin_clock=34, pin_cs=33)
, so now I wonder if the pin assignments in the example a right for the device. Any help?
RM2 Breakout example?
You will likely have to edit that line to match the pins used by the Plasma 2350’s SP/CE connector.
Right, makes sense, but the code wants 6 pin numbers, that list only has 5. Havcen’t found a clue yet for the pin number for pin_on, and the l;in number for pin_wake isn’t clear from the diagram.
thanks, I’ll continue experimenting!
What happens if you try one of these examples?

I have a Plasma 2350, but I don’t have the RM2 addon.
Try this :)

Was going to add the Plasma flavoured RM2 example to Github but looks like it’s already there :)
Excellent! That set of pin values worked. Not the same as the ones in the example on the pimoroni site and I’d NEVER have got them by trial and error. Thanks a lot!
