9. MISCELLANEOUS FUNCTIONS

Indication of Network Service Availability

The STAT_LED pin status shows information on the network service availability and call

status. In the LE910Cx module, the STAT_LED usually needs an external transistor to

drive an external LED.

The STAT_LED does not have a dedicated pin. The STAT_LED functionality is available on

GPIO_01 pin (by default GPIO_01 functions as STAT_LED)

See the AT Command User Guide for details about the AT#SLED section.

LED Status

Device Status

Permanently off Device off

Blinking

Blinking 1s on and 2s off Registered in idle

Blinking time depends on network

condition in order to minimize

power consumption

Registered in idle with power saving

Permanently on Not registered
