I solved it with a workaround:
1. send from leaf node a message to root
2. receive with root
3. open a socket and send to server

1. esp_mesh_send(NULL, &data, 0, NULL, 0); // send message to root
2. err = esp_mesh_recv(&from, &data, portMAX_DELAY, &flag, NULL, 0);
3. I used an lwip socket ...

Hello,
I'm trying to figure out what bluetooth channel is used by the ESP32 for the current advertisement scan (37, 38 or 39).
I couldn't find any API method for it and I couldn't extract any valuable information from the gap callback parameters (esp_gap_ble_cb_event_t , esp_ble_gap_cb_param_t ...

Meanwhile I switched from the python script to netcat:
nc -l -k -p 8089

And got this error message after the third esp_mesh_send function call (at the first two, nothing happened):
W (17492) mesh: [esp_mesh_forward_packet,206] [ucast]err:0x4012, ucast discard, xseqno:4, len:1502, 30:ae:a4:75:5c ...

Hello, I'm currently trying to modify the mesh example: https://github.com/espressif/esp-idf/tree/master/examples/mesh/internal_transceiver to send a messsage to my server, without success.

I checked the API's esp_mesh_send part: http://esp-idf.readthedocs.io/en/latest/api-reference/mesh/esp_mesh ...
