I am using an ESP32-S3 on IDF ver 5.5.0
I am in the early stages of developing a BLE Server for message data transfer.
I have been playing with the Example app ble_spp_server_demo and have tested this successfully with the iPhone nRF Connect app and it seems to meet my requirements.

WiFi Mesh MESH_NODES swithcing to closer Parents if low RSSI
I am using ESP IDF ver 5.5.0 and WiFi Mesh network.
My network is self forming with some node having a weak RSSI to their parent, and I want to lower this.
IDF API provides 2 function for controlling thresholds but little by way of description on how to use them.

How do I compress a bin file for OTA updates
I have a development project for ESP32 using IDF ver 5.5.0 in the vscode environment and have it working including support of OTA updates. I have read online that the project.bin file can be compressed for OTA transfer using the command:
idf.py gen_compressed_ota

MQTT TLS over ESP32 WiFi Mesh esp-tls-mbedtls: read error :-0x7180
I have an ESP32 project using MQTTS (TLS) through a Mesh network.
Everything use to work and I tested it with Eclipse Mosquito both TCP and TLS and HIVEHQ over TLS.
I was working on other aspects of the project for a while using a local LAN installation Eclipse Mosquitto over TCP. During this time ...

Has anyone found a BLE WiFi provisioning app which supports custom data
IOS / Android app for use with the example ESP32 software wifi_prov_mgr.
The ESP BLE Provisioning app does the basic provisioning but does not support custom data fields
Thanks

EPS32 IDF WiFi Mesh: Can my MESH_ROOT scan for Access Points
Is there a way for a MESH_ROOT to scan for Access points? I have read WiFi API functions should not be used while WiFi Mesh is active.
Is what I am trying to do below possible? Or maybe there is a better way to meet my requirement.
My requirement is to have 2 APs on site; a primary and a backup ...

ESP32 IDF WiFi BLE Provisioning with custom data
Hi
I am running the Espressif sample program wifi_prov.mgr under IDF ver 5.5.0 on an ESP32-S3 dev board.
I have not modified the sample source code and have the basic provisioning working using the iPhone app "ESP BLE Prov". I can scan the QR Code, select an AP and enter the password. My device ...

Questions regarding IDF docs description of esp_mqtt_client_init() config parameters
Hi
Can someone provide a more helpful description than the docs have of the MQTT esp_mqtt_client_config_t used in esp_mqtt_client_init(), specifically the following 3 parameters:
struct buffer_t
size //size of MQTT send/receive buffer
out_size // size of MQTT output buffer
struct outbox_config ...

Increase the WIFI_MESH MTU packet size so I can send larger MQTT messages
With the ESP-32 using IDF, is it possible to increase the WIFI_MESH MTU packet size so I can send larger MQTT messages across the WIFI_MESH network.
I thought (or hoped) the ESP library would break down the large MQTT packets for transmission across the WIFI_MESH network and they would be re ...

Re: ESP32 MQTT Paket size
I have not found this to be the case. If my MQTT packet size is larger than MTU, the transmission fails.
Am I missing something as this is what I really want?
