0x00: Request received, will disable UART now
0x01: Operation failed
0xFF: Operation not permitted
We insistently recommend disabling the UART using this command only, if it
is foreseeable that there will be no UART communication for several second-
s! Use cases could be during advertising phase to wait for connecting BLE
devices or when broadcasting data via Beacons.
Disabling the UART peripheral of the module results in a reduction of current
consumption of about 550µA.
Please note that the WAKE_UP pin has a second function. If the module is in
ACTION_SLEEP
mode, this pin wakes up the module by applying a low signal at
this for at least 5ms and releasing it to high. In this case, the module answers
with a
CMD_GETSTATE_CNF
.
7.5.7 CMD_UARTENABLE_IND
This indication is shown when the UART of the module is re-enabled (after performing a
CMD_UARTDISABLE_REQ
followed by using the WAKE_UP pin). After receiving this message
the UART can be used for any operation again.
Format:
Start signal Command Length Status CS
0x02 0x9B 0x01 0x00 1 Byte 1 Byte
Status:
0x00: UART has been re-enabled successfully
7.5.8 CMD_BOOTLOADER_REQ
This command resets the module and starts the OTA bootloader.
Please refer to chapter
14
on how to use the bootloader for a firmware update.
