WIRELESS CONNECTIVITY & SENSORS
User manual Proteus-II
We insistently recommend disabling the UART using this command only, if
it is foreseeable that there will be no UART communication for several sec-
onds! Use cases could be during advertising phase to wait for connecting
Bluetooth
®
LE devices or when broadcasting data via Beacons.
Disabling the UART peripheral of the module results in a reduction of current
consumption of about 1.15mA.
Please note that the
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
7.5.7. CMD_UARTENABLE_IND
This indication is shown when the UART of the module is re-enabled (after performing a
followed by using the
pin). After receiving this message the UART
can be used for any operation again.

7.5.8. CMD_BOOTLOADER_REQ
This command resets the module and starts the OTA bootloader.
Please refer to chapter
on how to use the bootloader for a firmware update.
Please note that you can only exit the bootloader mode by performing a hard-
ware reset using the respective pin.
