Flashing Sonoff 3.0 Version E

[apla2016]

How to flash Sonoff 3.0 Version E? I use to flash regular Sonoff with SmartRF Flash Programmer with no problem, but same procedure does not work with -E. Could it be that -E is built on other that CC2652P chip?

Yes, the -E is using a Silicon Labs EFR32 MG21 radio.

Thank you for super quick response. I tried this silabs online flasher, but it requires firmware in different format, not HEX that you developped. Anatoly

May be I did not get what you are saying. Are you saying to flash one of their firmware, or use their flasher to load your firmware?

This repo is not mine, it is also firmware only for TI CC based radios. The site I linked has firmware for the sonoff-E.

Sonoff ZBDongle-E (a.k.a. Dongle-E / ZBDongleE) by ITead indeed uses Silabs EFR32MG21 SoC and not radio chip from Texas Instruments.

Only ITead's Sonoff ZBDongle-P (a.k.a. Dongle-P / ZBDongleP) is based on the CC2652P radio chip from Texas Instruments.

To clearify; recommend use these unofficial community firmware builds for the Sonoff ZBDongle-E (a.k.a. Dongle-E / ZBDongleE) by ITead:

https://github.com/darkxst/silabs-firmware-builder/tree/main/firmware_builds/zbdonglee

For more information about using later Silicon Labs EmberZNet firmware with Zigbee2MQTT, see -> Koenkk/zigbee2mqtt#21462

Note that ITead/Sonoff themselves have not released any newer official firmware updates since that product was made available:

https://github.com/itead/Sonoff_Zigbee_Dongle_Firmware/tree/master/Dongle-E/NCP

Regardless,, it is specifically recommend to use a EmberZNet NCP firmware with 115200 speed for Z2M (not a RCP based firmware).

FYI, flashing of EmberZNet (EZSP / Ember) based adapters can also be done with thís Universal Silicon Labs Flasher (universal-silabs-flasher):

If you are using Zigbee2MQTT in Home Assistant then a tip is that there are several add-ons that are based on that for easier flashing:

https://github.com/tube0013/tubeszb_addons/blob/main/tzb-silabs-flasher/DOCS.md

https://github.com/mercenaruss/zigstar_addons/blob/main/zigstar-silabs-flasher/README.md

PS: Note that you first need to stop the Zigbee2MQTT application/add-on before you can flash the adapter.
