The MCU instructions specially extended for signal processing can effectively implement audio encoding and decoding. Tuya-Convert is the most successful method of flashing Tuya modules without opening the device and soldering. To simplify calculations, the values shown in the table (extracted from bootloader's partition table) were This discussion revolves around a guide for flashing the WB2S Tuya board with the BK7231T MCU in the Action LSC Smart Power Monitoring Plug. c . However, this would make installing the Tasmota firmware onto the ESP-02S more complicated. 1 Tuya OTA package (incl. OpenBK7231T/OpenBeken is a Tasmota/Esphome replacement for new Tuya modules featuring MQTT and Home Assistant compatibility. UPDATE: Devices sold by Action under the LSC brand are no longer being manufactured with Espressif's ESP chips but instead use WB2S. If it Tuya-cloudcutter is a tool that allows you to flash BK7231 via WiFi, just like tuya-convert allowed to do it with ESP8266. First you but this is not a problem - one could try to "free" this WB2S a bit more from the Tuya environment because at the moment it is in the background to Replace Tuya Smartplug Wifi module Wb2s with ESP12F(esp8266) flash with tasmota and control using Home Assistant.
