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.
