@mbarney, do you know if the REVX plan/sim card you had success with is the CATM version (50mb for $5) or the 4G version (10 mb for &12)? 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]

Thanks Anthony

I think it has been mentioned on other posts briefly, but if you are using a XBee3 Cellular LTE-M/NB-IoT modem make sure it is updated to the newest cellular firmware immediately ( A.02.19 firmware). A known issue on the early modem revisions was discovered which leads to corrupted memory in the ublox modem portion of the unit and they become…[Read more]

I have been testing out the solid-state rain gauge manufactured by Hydreon, model RG-15. The sensor works successfully as a drop in replacement for a standard tipping bucket style rain gauge both as a stand alone device using the TippingBucketRainCounter Master/Slave code and also with the ModularSensors code as Master, in both cases using th…[Read more]

Awesome I’ll head over there. 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]

No problem! Thank you for taking the time to look into it.

Thanks Sara! 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]

Hello,

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]
