DB (Cellular Signal Strength)
This command applies to the XBee 3 Cellular LTE-M/NB-IoT.
Reads the absolute value of the current signal strength to the cell tower in dB. If DB is blank, the XBee 3 Cellular LTE-M/NB-IoT has not received a signal strength from the cellular component.
DB0 only updates when the modem is registered with the cellular tower. It is updated periodically, and not when read.
