With the new modems I have not been able to register on the network (cereg 0,3) using the 4G plan and sim that worked for a couple years with the old xbee modem.

@shicks,  RevX systems technical support has…[Read more]

I made huge progress with the XBee LTEM. Have it working with just the reset jumper wire. I added a line to one of the .H files where the APN is set to hologram and also setupXbee() that sets the carrier profile to Verizon (not sure which one helped) and commented out some of the conditions from the example sketch…[Read more]

Thank you for taking the time to look into it.

Yes I have been over both the GPRS bee thread and the LTEM thread here on the forums and the Github thread a bunch. I added a crude “capacitor chain” with the recommended values between bee pin stubs power and ground, a jumper wire between reset and pin A5 and a capacitor on that reset jumper wire as well. It doesn’t fire up at all…[Read more]

I am testing a nearly identical setup to the showcased build “Construction of Water Level Monitoring Sensor Station” with the addition of a Maxbotix MB7389 and a Xbee LTE CatM1 instead of the 2G bee. I used code from baro_rho_correction.ino and menu_a_la_carte.ino.

When switched on the MayFly powered up and set up all the sensors, but…[Read more]
