I just received two of the new LTE-M development kits and I am not able to connect to the cellular network with either of them (AI=25). Also, the red LED on the XBIB board is lit solid (should be blinking) and the three green LEDs on the right are all lit. Here are the steps I’ve taken:
1. Connect to the boards using latest XCTU (works OK). SIM cards are installed, and antennas are attached to the correct connectors. Power supply and USB cables are attached.
2. Update firmware to latest version (1140B).
a. IP = TCP
b. TD = D
c. DL = 188.8.131.52
d. DE = 2329
e. AN = 10569.mc, –, or *
f. CP = 0, 2, or 3
g. AM = 0
If I check AI, it is = 22 or 25. At this location we have excellent Verizon and AT&T LTE coverage (DB=2D). I have also made a connection to Verizon’s LTE-M service with a competitor’s product at this same location. I also notice that PH and MN are coming up blank.
Is there something I haven’t done correctly? Does the SIM card need to be activated? We’re anxious to get this working!
