ESP Zigbee Gateway example failes with host mode uart not supported (ESP32S3 + ESP32H2) (TZ-1487)

[czagaadam]

Hi mates!

I've seen that similiar issues are already raised in github but I haven't found a proper solution.
So I'm using an ESP32 S3 (WROOM 1) with the esp_zigbee_gateway code and an ESP32 H2 (MINI 1) with esp_zigbee_rcp code.
H2's RX and TX pins are connected with S3 PIN 4 and 5, but I don't think this would be the issue.

When I launch the monitor for S3 in VSCode I'm getting this error message:
host mode uart not supported

Please let me know what is the issue and how can I resolve this.

@czagaadam ,

Could you please follow the setup README of gateway to test again?

Okay I tried, it seems my original Gateway example on S3 was outdated because this new one is much longer:
https://github.com/espressif/esp-zigbee-sdk/tree/main/examples/esp_zigbee_gateway
Although it is still not working, I'm getting this in Monitor:

I updated H2 with ot_rcp example, and here is what I'm seeing in Monitor:

S3 pin config:

H2 pin config:

For me the RESET pins seems working because H2 is resetting again and again but serial connection seems wrong.
In H2 logs: rst:0x1 (POWERON),boot:0x4 (DOWNLOAD(USB/UART0)) means that H2 waiting the update in UART0?
As it can be seen in pin config I redefined H2's UART to pin 4 and 5, is it problem ?

Hi,

Could you try using the default TX/RX pins of the RCP for testing? or disable the ZIGBEE_GW_AUTO_UPDATE_RCP in menuconfig.

[czagaadam]

I tried with H2's default TX RX pins (GPIO 24 & 23) with both ZIGBEE_GW_AUTO_UPDATE_RCP disable and enable.
That's what I've got:

(PermissionError(13, 'the device does not recognize the command ', None, 22))

Should I try shorter jumper wire or lower the baud rate ?
I'll also check the connection with uart analyzer.
