Low cellular signal strength with xbee modem, no internet connection is possible

Question

I use the XB3-C-A2-UT-001 with MicroPython since a while. Now the cellular signal strength drops down suddenly, so that an internet connection is difficult to obtain. But in the same time I tested the same SIM card in an other device, and the signal strength remains OK. What could be the reason that the signal strength of the modem is far worse than the same signal strength of an other device at the same place. Is there a receive/send power, that we could set in the XTCU configuration?

Even when the signal strength is bad (for ex 0x5B), is there a possibility to force a cellular connection? Because in our case, the “while not c.isconnected():” loop is running indefinitely.

Thanks for your help.

Answer 1

No there is not a way to Force a Connection. It is the tower that determines if a connection will occur.
