NimBLE - ESP32-S3 - ESP IDF - blecent example transmission is slow

Hi, I try to send 60kByte of data over BLE between two ESP32. As a start, I used the blecent example from NimBLE/ESP-IDF and so far the communication works great and reliable, but the speed is extremly slow. It seems, that I can only send exactly every 100ms a packet and I really don't see, where I ...

ESP-IDF: Bluedroid Host Subsystem Deprecated?

Hi I would like to use a BLE Stack for a ESP32-WROOM-32UE-N4. ESP-IDF supports two stacks, once the BlueDroid and then the NimBLE. When I check the BlueDroid Design on https://launchstudio.bluetooth.com/ListingDetails/124622, it is deprecated and no new products can be release after 2023-02-01 when ...

ESP32 Exception Interrupt WDT Timeout

Hi, I'm using a ESP32 for some IoT with MQTT and it works pretty good so far, but around once a day the following occurs on each ESP32 (randomly) : Meditation Error: Core 1 panic'ed (Interrupt wdt timeout on CPU1) I'm not sure if this is caused by the logging process itself (will be disabled later) ...

WiFi with timer interrupts sometimes throws a meditation error

Hi, I'm using a ESP32 for some IoT with MQTT and it works pretty good so far, but sometimes one of the ESP32 goes into a hardfault (Guru Meditation Error: Core 1 panic'ed (Cache disabled but cached memory region accessed)) and I don't really know what I could do against it. It mostly happen, when I ...

ESP-IDF BLE bonding only when additional a button is pressed

Hi, I have a central and a peripheral where the peripheral is advertising until a central finds it and connects. Now I have already bonding implemented and on the central, the coupling must be accepted but is it somehow possible, that also a button input needs to be read on the peripheral to complet...

ESP-IDF BLE unauthenticated device sends data within 30s

Hi, I try to use the gatt_security_server example in my project to achieve bonding and it works fine so far. When I connect over the nRF Connect App from Nordic, a secure connection is etablished and the device is bonded. But when now third party device connects, which does not support bonding, it s...

Re: BLE mash - persistent provisioner

Any update yet? I need this functionality too, otherwise it does not make much sense to use a provisioner, that can't hold the network information persistently.

ESP IDF BLE mesh vendor client example persistent memory

Hi, I tried out the BLE mesh vendor server/client examples and it works fine so far. The problem i encountered is on the client side (provisionier), such that after a restart, the node informations are gone. In the IDF menuconfig, the option "Store BLE Mesh configuration persistently" is activated o...
