Serial Flash
Download tasmota32-zigbeebridge.bin unofficial precompiled firmware from development branch and flash the ESP32 module.
Flash Zigbee module
Download Zigbee module firmware (for example: ncp-uart-sw_6.7.8_115200.ota) from Tasmota GitHub located in Tasmota/tools/fw_SonoffZigbeeBridge_ezsp/.
Go to Firmware Upgrade and next to “Upgrade by file upload” use the Choose File button and select Zigbee module firmware you downloaded f.e. (ncp-uart-sw_6.7.8_115200.ota).
Click on Start upgrade, be patient and wait for a few minutes until flashing is complete. Once it is done, Tasmota will reboot. If the flash was successful the console will show Zigbee2Tasmota starting:
