BK7231N - Universal IR Remote Contorl
disassembly pictures:
December 2022 update:
* the IR blaster is now working (firmware 1.15.x , i tested mine on 1.15.226)
* this device is Model S08 / PCB: S06-CBU-V1.2
* all the pins needed for flashing are easily accessible on the board (TX1,RX1,GND,3.3v and CEN for reset)
* After flashings set pins as follows and restart the device! (IR pins are not changed at real-time)
* Testing the IRRecv: go to the webapp log and shot some coded for external remote, you should see something like that:
* Testing the IRSend: copy the protocol and command from the log to create ir-send command as in the example below

There should be no problems with IR soon, just wait. I will try to order such a device for testing, if I find it somewhere with cheap shipping to Poland. Can you also do a flash dump for tuya-cloudcutter? I... [Read more]
Just bought one, £8.50 delivered to UK :). Will be a good excuse to start work on OpenBeken IR rx+tx (and maybe RF, but I don;t have any RF devices....). [Read more]
Yes, let's get IR working! I will also buy that one. But wait... can't we just get any IR receiver module (even one from old CRT TV) and use that for testing? I have tons of them. [Read more]
I think you can just connect any IR receiver and IR transmitter from any remote to test it out with beken chip similar to esp [Read more]
@pkaczmarek2 If I understand correctly - the latest releases, 1.4.24, have support for IR receiver and transmitter? I have!!! Judging by the PCB, USB data is being used. [Read more]
@omelchuk890 you are seeing correct, although it is a preliminary development version. Please wait few days. @ferbulous I'm on it. Here are some random photos from IR testing, my IR parts collection,... [Read more]
@pkaczmarek2 great work on ir component! Looking forward to try it once it's stable [Read more]
@ferbulous we're working on it, but it's T only so far. Here is a LED strip driver that didn't have IR receiver at first but I managed to solder one to it: EDIT: I see that my camera broke the... [Read more]
Tested on firmware 1.14.42 - reception is working, data in MQTT is leaving. How do I send a transfer command via MQTT? @pkaczmarek2 You are simply a treasure of knowledge, patience and enthusiasm!!! P.S.... [Read more]
Thank you. Yesterday we had to increase the stack size slightly to prevent potential, exactly, freezes, that happened to us in multiple places. Today I also added a MQTT deduper, which prevents things... [Read more]
@pkaczmarek2 I constantly receive it with variable frequency. [Read more]
This looks very promising! I have the same IR blaster as yarix2 (the s06-CBU-v1.2 board) and successfully flashed it with OpenBK7231N. Does anyone know what settings you should use for the IRsend and IRRecv... [Read more]
Hello @avdm . The N platform requires a timer adjust which has not been done yet, but @btsimonh has just received his N IR receiver today, sooo I hope this will be resolved soon. Please wait several days,... [Read more]
Thank you for the update, I appreciate it! And you are absolutely right. After some power resets the device came back to life. I've ordered 2 extra (Got a great deal: 2 for less than €13) so I can... [Read more]
I think that @btsimonh got IR working on N today. It was just a little fix related to timer. It should be possible to receiver IR on both T and N now. Only MQTT rate improvements are pending. If you spam... [Read more]
