By updating the firmware of the Rf chip (or co-processor, microcontroller) EFM8BB1 new possibilities become available. Starting with Tasmota v6.0.0a the Rf chip firmware upgrade is easily done using Web Gui Upgrade by File Upload. Tasmota currently support the Portisch (https://github.com/Portisch/RF-Bridge-EFM8BB1) firmware only.

A hardware preparation is needed (only for R2!) if you want to use USB for powering the device during EFM flash process. ## Flash-Process of Hardware R2 with Hardware preparation
Shown picture is the Bridge R2 version where two not used copper traces need to be cut if you want to use the current power connector during updating and connect two wires between GPIO4 and C2Ck and GPIO5 and C2D. These changes can be permanent as they do not interfere with the normal Bridge functionality and it also allows for easy changing of firmware in the future. _This chapter applies only for R2 and only if you want to use USB for powering the device during EFM flash process._

**You dont have to cut wires to upgrade the firmware of R2!!!!** **You dont have to cut wires to upgrade the firmware of R2!!!!**
If you dont like the idea cutting something in your bridge there is no need for! In that case DONT use USB to power the bridge. Power the bridge over a pin in the bridge labeled 3.3V. Just the same way as flashing the ESP. However you still need to connect GPIO4 & GPIO5 as described above. If you dont like the idea cutting something in your bridge there is no need for!

After flash process is done the bridge can be powered over USB for normal use. After flash process is done the bridge can be powered over USB for normal use.
Once the hardware changes have been made or the Bridge is powered via a 3.3V pin and the correct Tasmota firmware has been uploaded select the desired RF_Bridge.hex firmware file from the tools/fw_efm8bb1 folder and Start upgrade. This will replace the current Rf chip firmware within 60 seconds.
