are you holding the EBOOT button down when plugging in the device to flash? (you can also hold it and tap the ERST button to reset the esp32 into bootloader mode).

esphomeflasher.exe --port COM5  --upload-baud-rate 115200 Downloads\tube-zb-gw-cc2652p2-v2_2021_09_17.bin

[mcarbonneaux]

is needed to flash also the ti part (CC2652) or is pre flashed?

[tube0013]

The cc2652 is pre-flashed.

[mcarbonneaux]

erst tryed and not permit to flash...

" zigbee over usb " how to try that ?

ok is to use the coordinator usb zigbee dongle for z2m or zha ?!

[tube0013]

you can go straight to ethernet now if you have the wt32-eth01 flashed and installed.

guides are on the site and z2m has docs for setting up a network connected coordinator (skip to step 3 on that page).

i while test that tomorow ! :) i flashed the second one too with success!
