Operating modes

IoT Modules RC76
1

Hi,

I am using AT+CFUN to set the operating mode for my LTE modem. I have RC7620.
The modem seems to allow following modes

// Minimum Functionality
AT+CFUN=0

// Full Functionality
AT+CFUN=1

// Low-power
AT+CFUN=4

// Factory test
AT+CFUN=5

// Reset
AT+CFUN=6

// Offline
AT+CFUN=7

What is the difference between AT+CFUN=0 and AT+CFUN=4?
Both modes seem to behave like ‘low-power’ mode.

Thanks
Sai

Hi @saim ,
According to the AT Command Reference Guide, the RC7620 only supports cfun=0 (minimum functionality) and cfun=1 (full functionality)
For more details, please refer to Section 18 - Supported GSM/WCDMA AT Commands on page 8 in the link below:

Yes I saw that, but the modem seems to respond to more values than what is mentioned in the AT command manual.

Hi @saim ,
Basically, Sierra highly recommends customer use AT commands which are described in AT command document. In case, you would like to use some un-documennted commands, please contact technical support via email to support@sierrawireless.com for further support.

Thanks,
