    if I try to send - say "OK", no actions on contioner.

Topic summary

The discussion centers on the BK7231N-based universal IR remote control devices, particularly models S08 (PCB S06-CBU-V1.2/V1.3) and iH-F8260 (PCB v4), focusing on hardware disassembly, pin configurations, firmware flashing, and IR functionality. Users share disassembly images and pinouts, highlighting accessible flashing pins (TX1, RX1, GND, 3.3V, CEN) and IR-related pins (IRSend, IRRecv, wifiLed). Firmware versions from 1.14.x to 1.15.x are tested, with IR receiver functionality confirmed on pin 8 (P8) and IR transmitter on pins 7 or 26 depending on the model. IR send commands use syntax like "IRSend NEC-1-14-1" via console, HTTP, or MQTT (topic format cmnd/device/IRSend). Challenges include device freezing, noisy IR reception (notably RC5 protocol interference), incomplete IR protocol support (especially for AC remotes like Mitsubishi, Samsung, Daikin), and inconsistent IR transmission reliability. Protocol filtering and inversion of IR output signals are discussed to improve performance. Firmware updates and pull requests aim to expand supported IR protocols, align with libraries like IRremoteESP8266 and Tasmota, and enhance MQTT integration with JSON payloads for IR events. Users report successful flashing using tools like uartprogram and BK7231GUIFlashTool, and integration with Home Assistant via MQTT. Ongoing development addresses IR send stability, protocol filtering, and expanded AC remote support. The community shares scope measurements, command syntax clarifications, and troubleshooting tips for pin assignments and device recovery modes.
