10.7Indication of network service availability

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

In the GE863 modules, the STAT_LED usually needs an external transistor to drive an external LED. Therefore, the status indicated in the following table is reversed with respect to the pin status.

LED status

Permanently off

Fast blinking (Period 1s, Ton 0,5s)

Slow blinking (Period 3s, Ton 0,3s)

Permanently on

Device Status

Device off

Net search / Not registered / turning off

Registered full service

a call is active
