8.3.2.5.3.6 Read Back Updated Firmware Version
In the proceeding step, the central device tries to read back the newly updated firmware version of the remote device.
The user can achieve this by following through the initial OTAPC firmware update method. As the Bluetooth Low Energy connection link already exists between both devices, the central device initiates a firmware update request again. The response from the remote device has the updated firmware version.
For that, the same procedure of firmware update approval with OTAA,01
from the remote device is necessary.
Follow the same procedure described in 8.3.2.5.3.4 Firmware Request Approval.
