- The cutting and soldering of the Mayfly and XBeee adapter mentioned above works great! I can now programmatically reset the modem if it gets into a non-responsive state. I’m thinking of ditching my Sleep Mode code and instead doing a Shutdown(SD) and power off via A5 between communications. It may be less error prone and it does use slightly less power. So far my experience is that it reconnects quickly.
- CP=1 has been working. I’ll know better after a week of continuous testing 2 Mayflies – one with modem at FW-11413 and the other with 11415.
- For Matt – maybe you are right that PSM is getting “stuck”. From the manual:
Note The cellular module comes out of the PSM low-power state whenever any network activity occurs, including Remote Manager activity
I have code that does a Lookup Address (LA) whenever AI=2C (PSM). That should get it out of PSM – and I’ve seen it get triggered on occasion. But if the XBee is getting stuck in PSM, I now have the ability to power cycle the XBee, that should work around this problem.
