Introduction
This document describes a common procedure to perform Over-the-Air (OTA) firmware upgrade of Flairmesh’s Bluetooth modules and USB dongles.
Preparation
To make the, we need an iOS App “GoFlooGoo” from Apple’s AppStore. The direct link is, https://apps.apple.com/us/app/gofloogoo/id1621927554
Configure Target’s UUID128 in GooFlooGoo
After installing “GoFlooGoo”, before open it, we shall configure its BLE
service UUID128 so it only searches and connects to the expected module or
dongle.
Go to the “Settings” of the iPhone and search for “UUID128”, open the item of
“UUID128/GoFlooGoo”, and set the value as Table 3.1.
Table 3.1 Default BLE GATT Service UUID128
| Model | UUID128 | Comments |
|---|---|---|
| FMA100 | F455A208-5970-11EC-BF63-0242AC130002 | |
| FMB100 | 1AAA5F34-3A93-4B89-B05B-1B4A89930CE0 | The UUID128 can be read by |
“BC:LU” command on its UART interface. Refer to the programming interface
manual.
FMD100| 1AAA5F34-3A93-4B89-B05B-1B4A89930CE0| Same as above.
OTA Procedure
Run “GoFlooGoo”, click the “New Paring” button at top-right corner to connect the device to be upgraded.
When connected, the “Upgrade” button turns on. Click on it opens a file browser. Choose the “*.bin” firmware file that has been copied onto the phone, in the screenshot a firmware “FMA100_1_2_2_6…bin” on the Cloud drive is shown as an example. Click on the file starts the OTA procedure, shown as an example. Click on the file starts the OTA procedure,
When the progress reaches 100%, the device will validate the firmware
(5~10seconds) and then reset itself, the connection will break for several
seconds and resume. After reconnected, the state shall become “Ota Done”
which indicates a success. After that, the device will reset itself again to
fully shift onto the new firmware. In the following screenshot that excluding
the first “1.2.2.6” (which shall be the original firmware version for the
device), there’re two of “1.2.2.6” (which is the new firmware version after
OTA, it’s harmless to perform OTA on the same version).
When it reaches here, it’s done and click the button “Remove Paired FlooGoo”
to disconnect with it.
If any error happens, the device will return to the old firmware after the
failure. The bootloader always checks and only switches to the new firmware
after a successful verification. A new OTA can be performed once it resumes
working and connectable in the old firmware.
