Hello.

$cm radio on
$cm radio
Power: OFF
Current Network Operator:
Current RAT: Module not registered on network, RAT not available
Status: Not registered and not currently searching for new operator (LE_MRC_REG_NONE)
Signal: No signal strength (0)
PS: Packet Switched Unknown state (LE_MRC_REG_UNKNOWN)

i get log where “power off”.

how about using AT command?

AT+CFUN=1

Also please check the following:

AT!ENTERCND=“A710”
AT!IMPREF?

AT+CFUN=?
+CFUN: (0-1,4-7),(0-1)

OK

AT+CFUN=1

AT!IMPREF?

AT!ENTERCND="A710"

can you try some old FW and see if it works:

could you specify which FW ?

maybe the generic one
