Re: NVS Encryption (idf 4.0 -> idf 4.4)

Hi SlavaDev503, Sorry for the inconvenience during the upgrade. We haven't considered the use case that one NVS partition may be encrypted and the other not encrypted! You can call nvs_flash_init_partition(NVS_DEFAULT_PART_NAME) instead of nvs_flash_init(). Unlike nvs_flash_init_partition, nvs_flas...

Hello. Our device based on esp32-wroom 32d uses BLE to interact with mobile phones. Flash encryption is enabled in firmware. We faced with problem when we update firmware to new esp-idf v4.4 from esp-idf v4.0. The problem is the list of stored bonded BLE devices. After update all previously bonded d...

Re: how to include esp32 ble component in a custom component

It seems that your bluetooth disabled, you need to enable it in menu config, you should not directly add it in your cmake.

UART clock source

Hello. ESP32 communicate with host over UART0 using custom binary protocol with CRC validation. If I use 200K baudrate, the link is ok. When I increase baud to 1M baud communication is still works, but it is very unstable, very often i get message "CRC invalid". When I sniff data exchange, I saw tha...
