Connectivity issue with CC2652P2 Ethernet/USB Coordinator after some minutes

[didles]

Hello,

I ordered a CC2652P2 based Zigbee to Ethernet/USB Serial Coordinator beginning of Feb 2022. It was working fine until last week when I lost ethernet connection regularly. Need a power on/off to have it up again during a few hours or minutes. Then I removed the WT32_ETH01 board. Without this board, the zigbee part is working fine connected via USB (several days without issues).

If I power the WT32_ETH01 separately and connect to ethernet, then pinging stops after some minutes.

So seems an issue with either the WT32_ETH01 board or with the ESP software.

Any idea to investigate more this issue ?

Regards

Didier

try a serial reflash of the esp32. have seen them get into a funky state and and a reflash helps.

stock esphome fw image is here: https://github.com/tube0013/tube_gateways/tree/main/V2_tube_zb_gw_cc2652p2/esphome

Flashing mode:

https://github.com/tube0013/tube_gateways/tree/main/V2_tube_zb_gw_cc2652p2#esp32-flashing-mode---esp32-serial-connection-via-usb

Hold the BOOT button while plugging into USB

troubleshooting doc has a flashing section and links to the esphome flasher tool: https://github.com/tube0013/tube_gateways/blob/main/Troubleshooting.md

Thanks, I will try, I need first to buy the USB to serial adaptor.

Note that the green led on ethernet jack continues to blink when I have the issue, so the software is not completely dead.

Nope - not with the model that works via usb or network like you described

you can just change the jumpers as shown so onboard serial talks to the esp32.

you do have to trigger the boot mode by holding the boot button on the main PCB when plugging in the USB cable.

Same issue after reflashing. It is working for some minutes ( ping is ok), then it stops and I get in debug console:

[W][ethernet:115]: Connection via Ethernet lost! Re-connecting... [W][ethernet:106]: Connecting via ethernet failed! Re-connecting...

can you send me a note at store@tubeszb.com so I can look up your order. I can send you another WT32-ETH01 module as it seems this one has issues. Or you can look to pick one direct from Aliexpress.

I have used about 50 of those ETH01 boards. I can share they definitely need a bit of power for Ethernet. I have experienced connection loss and brownouts when not using at least 2amp of power.

Hello Michael, I connected the ETH01 to a Lab PSU ( can give up to 3A ). I get 120 mA max at 5V, and still have same issue after a while. So seems not to be a power supply issue.
