L610 module supports two ways to enter the flight mode:
1
Hardware I/O interface
button control
Pull up the W_DISABLE# signal to enter the normal mode, pull it
down to enter the flight mode
2
AT command control
AT+CFUN=4--enter the flight mode
AT+CFUN=1--enter the normal mode
3.8.2 Sleep Mode
For details of sleep mode, refer to FIBOCOM L610 & LC610N & LG610N Series Sleep Test Guide.
3.9 ADC Function
L610 provides three ADC interfaces. Use AT+MMAD=<index>, <index>=0, 1, 2 to read the voltage value
on each ADC. The ADC range is 0-VBAT, the precision of ADC are 11bits.

Note:
If there is a high requirement for accuracy, it is recommended to use low gear.
Ground isolation is recommended for ADC layout to improve ADC voltage measurement accuracy.
When using the ADC function, a 1KΩ resistor is required to be connected in series.
3.10 Analog Audio Interface
L610 support analog audio input and output. Module built-in Audio CODEC chip inside, one differential
MIC input, one differential SPK output and two headphone outputs. Users can connect MIC, SPK and
headphone directly to the module, also can add an audio amplifier as required.
