Hi team, I have one SonOff RF Bridge R2 working with ESPurna firmware. Hardware NOT MODIFIED.
I made and upgrade loading latest RFBRIDGE_OpenMQTTGateway_V092.bin firmware from OMG with my tasmotize software and mi FTDI connected at GND/RX/TX/3V3 pins on the board.
- Unplug the board
2.Plug the FTDI pins
3.Move the board switch to OFF
4.Press and hold the reset button (pairing button)
5.Power the board via FTDI
6.Wait for 5 sec and release the reset button
7.Starts TASMOTIZE and flash the board
Flashing OK and, then, power off FTDI, unplug it, move the switch to ON and plug the board to USB power.
Only the SonOff Logo LED lights…nothing happens…no SSID, no Wifi LED…
I tried to reflash it again with ESPurna, OMG, original firmware…but it was impossible!!! The board doesn’t responds!!! TASMOTIZE software says that there is NO Serial connectivity to the board.
I tried with another flashing software and another FTDI device…nothing works.
I seems that, after OMG flashing, the device is out of service…and I can’t recover it !!!
