Preliminary
DLBM-CG121
13.11 Using Low Power Modes with the AT command set
Since the standard UART protocol does not allow for the retry of transmission when information
is lost over the UART, DLBM-CG121 uses a specific set off instructions to cause the device to
exit out of deep sleep.
The software recognises the AT command “AT+CWUP” from the host and will respond with a
“ WAKEOK= <expected minimum wakeup time”. Therefore the host can issue the AT+CWUP
command repetitively until it receives the WAKEOK command response. The parameter which
is associated with the response, indicates the minimum time that the DLBM-CG121 will be
awake and is sent in millisecond units. Therefore the host does not have to send AT+CWUP
commands during this period. To reduce latencies, it is possible to re-transmit the second
AT+CWUP command within 100ms of the first AT+CWUP command since there will be a high
probability that DLBM-CG121 would now be awake. Thereafter it is suggested to wait at least
5000ms between subsequent AT+CWUP commands in order for DLBM-CG121 to respond.
