TC63i AT Command Set

TC63i AT Command Set
19.3 AT^SBC
Notes
• If multiplex mode (AT+CMUX) is active, any virtual channel can be used for entering the read or write command.
The undervoltage URC will be issued simultaneously on all three channels.
• Another URC type required for battery powered applications is the URC "^SYSSTART CHARGE ONLY MODE".
It is indicated automatically when the module enters this mode (except when autobauding is active). See
AT+CFUN for details.
19.3.1 Responses returned by read command
Responses returned by the AT^SBC read command vary with the operating mode of the TC63i:
• Normal mode: TC63i 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 ).
• Normal mode + charging: Allows charging while TC63i 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 TC63i 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 TC63i was powered down with AT^SMSO
- from Normal mode: Connect charger, then enter AT^SMSO.
