Table 9: <RX_channel> parameter range

The "+CME ERROR: operation not supported" or

"+CME ERROR: 4" error result code will be provided in

these cases (depending on the +CMEE AT command

setting):

o A value not belonging to the above ranges is

set

o The RX channel parameter value belongs to a

non-supported RAT (2G or 3G or 4G RAT) or

band

The default channel will be equal to 32 if the GSM

RAT is supported, in the other cases it will be the

same as the central channel of the lower LTE band

supported by the module.

<RX_time_

interval>

Time 1 ÷ 600000 1000 Time interval for RX test expressed in ms

<receiver_

path>

Antenna diversity 0 ÷ 1 0 Receiver path:

o 0: main / primary antenna

o 1: diversity / secondary antenna

The parameter is available only if supported, otherwise

an error result code will be provided ("+CME ERROR:

operation not supported" or "+CME ERROR: 4" depending

on the +CMEE AT command setting)
