> 19.3.1 | Responses returned by read command

> Responses returned by the AT^SBC read command vary with the operating mode of the TC65:

> • | Normal mode: TC65 is switched on by Ignition pin and running in SLEEP, IDLE, TALK or DATA mode. Charger is not connected. The AT^SBC read command indicates the battery capacity and the current consumption of the application (if value of application was specified before as <current>).

> • | Normal mode + charging: Allows charging while TC65 is switched on by Ignition pin and running in SLEEP, IDLE, TALK or DATA mode. The AT^SBC read command returns only charger status and current consumption of the application. Percentage of battery capacity is not available.

> • | CHARGE ONLY mode: Allows charging while TC65 is detached from GSM network. When started, the mode is indicated by the URC "^SYSSTART CHARGE ONLY MODE". The AT^SBC read command returns only the charger status and current consumption of the application. Percentage of battery capacity is not available. In CHARGE ONLY mode a limited number of AT commands is accessible (see Appendix). There are several ways to activate the CHARGE ONLY mode:

> - | from POWER DOWN mode: Connect charger while the TC65 was powered down with AT^SMSO

> - | from Normal mode: Connect charger, then enter AT^SMSO.
