@SillyDay Any tip on where to find wow-to flash instruction in English to add to the README.md file?

PS: Ordered mine from China but feels like if will take forever before will arrive in the European Union.

@SillyDay Taught I just ask if you would mind helping out Tasmota developers with building Zigbee coordinator firmware images with the EmberZNet Zigbee stack for EFR32 based Sonoff ZBBridge?

From their discussion it does sounds as if they need a firmware image that includes Bootloader, see:

arendst/Tasmota#8583

Sonoff ZBBridge is an inexpensive EFR32MG21 & ESP8266 based Sonoff branded Zigbee Bridge by ITead

s-hadinger wrote this today regarding pin definition

the complete EFR32 module pinout and ESP8266 connection is as follows:

• PB01-TX + PB00-RX, pads ETX+ERX, connected to GPIO1+3
• PA00, no pad, connected to GPIO5
• PA01, pad SWCLK, not connected to ESP
• PA02, pad SWDIO, not connected to ESP
• PA05, pad Z_TX/PA05, not connected to ESP (EFR32 console)
• PA06, pad Z_RX/PA06, not connected to ESP (EFR32 console)
• nRST, pad Z_RST, connected to GPIO4`
• no other EFR32 pin connected

@SillyDay First of all, thanks for this!

Would you mind including versions information, like exactly which version of the SDK used, which version of EmberZNet PROD Zigbee stack, and versions of other dependencies so others can if they want lookup what affect what feature and function or bug-fixes was included in these images?

It would also be nice if included any information about the config used when building these.

Thank you again!

Can you please confirm the serial port baudrate?
I've successfully flashed it on E180-ZG120B-TB board, but cannot get reply to Reset EZSP frame. Using 57600 baudrate.

I've tried compiling the bootloader, but don't have luck with that either. Seems like i'm missing something obvious.
