Hi, its not that i dont want to help you, but i believe it will be faster and with better results to you when you start from scratch. - grab espressif example - in custom callback (esp_ble_mesh_register_custom_model_callback) just print logs for event and opcode to see what you are receiving and to ...

It would be best to describe:
- example code or source code you are using
- problems and/or issues you have
- steps you tried to make it work, including provisioner used to provisioning
- any extra info which can be helpful

You should read that news.
BLE 5.0 certification is due to ble mesh support. There is no long range, 2mbit PHY etc. Those are only available in newer chips like S3, C3, H2.

First, I don't understand why Sensor Data doesn't match the Message field. Also, what is this warning message about outbound bearer? I thought that 0xFFFF refers to all nodes in the network, but when I try to handle the publish message in the client code, it acts like no message has been received a...

Thank you for your input. While I understand the concern about ensuring the WiFi connection is fully established before initiating OTA, I've verified that the WiFi connection is indeed stable and operational. Despite this, I'm still encountering the "ESP HTTPS OTA Begin failed" error. Are there any...

It is very simple, just compare both functions: esp_err_t esp_ble_mesh_server_model_send_msg(esp_ble_mesh_model_t *model, esp_ble_mesh_msg_ctx_t *ctx, uint32_t opcode, uint16_t length, uint8_t *data) { if (model == NULL || ctx == NULL || ctx->net_idx == ESP_BLE_MESH_KEY_UNUSED || ctx->app_idx == ESP...

Its how USB library in arduino is prepared.
If you enable DFU then additional endpoint is added to your code.

It all depends what is the area on which all the devices will be placed. 100+ wifi APs its a lot and if you dont implement it really good all will be stick to the same channel. It is hell a lot of noise and RSSI wont be reliable most likely. If you add people with bluetooth devices around (just gues...

I am wondering when espressif start advertising ESP32 as USB capable, like they did with bluetooth and after adding ble mesh ESP32 become bluetooth 5.0 certified.

In your case i would just make softAP ssid based on MAC address, so every device would have different SSID and RFID sticker on it or even better with QR code. Sure, its not best solution if you have 100 devices, but you can easy write app on smartphone which can read RFID or QR code and connect that...
