Hello I’m a complete Newbie,
I have built a board with a Q2686, sim card and max3232. I have inverted both Rx/Tx and RTS/CTC thru the max3232.
All seems to work OK. It registers on the network and responds to AT commands. I have compiled the hello world program which downloads with no errors and have set it running. eg.
However there is no serial or Trace output.
Is there something basic I am missing?
I have used both Open AT V2.30 and AT V2.21 with the same result
Any ideas would be appreciated
