Flash and use the Sonoff RF Bridge R2 V1.0 to control RF devices

Using a serial-to-USB converter (FT232RL FTDI USB to TTL) and some dupont wires flash the R2 V1.0 RF bridge ESP with Tasmota, flash the RF chip with the custom Portisch firmware, then reflash the ESP with ESPHome.

• Download ESPHome-Flasher
• Download tasmota.bin from Tasmota releases
• Download the entire contents of the Tasmota GitHub project via the green Clone or Download button to ensure that the firmware hex files are downloaded properly. The firmware files are located in the ./tools/fw_SonoffRfBridge_efm8bb1/ folder. Select the newest available hex file. Otherwise you may get error "Magic byte is not 0xE9".

• Remove the rubber feet from the Sonoff RF Bridge, optionally placing them just next to the screw holes
• Pull out the circuit board from the casing
• Lift up the led panel from the circuit board, carefully unsticking it
• Locate the 5-pin header under near the bottom of the bent up led panel
• Move the switch position towards the 5-pin header (to the off position)
• Attach the dupont cables to the serial-to-USB converter
• If the green led panel lights up and there is no blue flashing light then it is in programming mode
