Uni1 remote V2 and its receiver (built in Ubox or standard one) have built in bootloader, so we can upgrade their firmware when new feature added or for fix issues.
The upgrade is through USB cable with a PC app, the remote is integrated a USB to UART bridge chip, CH340. The remote is directly upgrade by USB cable connection, the receiver's upgrade is relied by remote through their RF inter-communication.
Prepares
The receiver's wireless upgrade requires: a windows PC, a Uni1 remote V2, a USB cable with a type-C connector.
CH340 driver download:
https://github.com/JohnSpintend/Remote-receiver-FW/blob/main/receiver/CH341SER.ZIP
PC APP download:
https://github.com/JohnSpintend/Remote-receiver-FW/blob/main/receiver/RF%20Upgrader%20V0.92.exe
Firmware download:
Install driver
Install the CH340 driver, CH340 is the remote’s internal USB to UART bridge.
Run the ‘CH341SER.EXE’.
Click ‘安装’
Click ok.
Power on the remote, connect it to the PC with USB cable, go to windows's Device Manager, Win key + R, then type in ‘devmgmt.msc’ and click ‘ok’.
In the Device Manager:
check the Ports list, to find a COM port named with ‘CH340’. The number will be used in upgrade APP.
Upgrade FW
Go into Remote's setting menu->Receiver Config->Receiver Upgrade, click ENTER.
Run "RF Upgrader V0.92.exe" on windows PC.
Choose the COM port, and choose the file with ".binpak" extension.
Click "Upgrade" or "Auto" button.
Connect Ubox with a power source, stay close with remote, then hold the power button, don’t release it, the RF Upgrader will start to download the new firmware into the receiver.
Finished, click ok, release the power button, EXIT upgrade on the remote, then do next one. When all finished, click the Close COMM button on the RF Upgrader APP, then close the APP.
Concludes and explain
- The bootloader work within a 0.3-0.5 second time window to check if there is a upgrade packet send to it. So we need to give the receiver a re-power on. For Ubox V2, we can re-power on it, for a standard receiver, we can re-plugin its cable in to a VESC to get re-power on.
- If the RF Upgrader APP has some errors can't be quit or closed, use task manager (ctrl + shift + esc) to end it manually.
