Hi everyone, recently I purchased a Type C IR Blaster (
https://de.aliexpress.com/item/1005006058268428.html?gatewayAdapt=glo2deu).
It works on an Android with their application Ocrustar.
However I want to make it work on a raspberry pi or microcontroller.
I pried open the IR Blaster and in it I see a microcontroller WCH 552ED06. But I can't find any documentation on this chip.
I did some research and think that it could be a chip which provides USB + IrDA (some kind of IR Specifications)?
My next step is to somehow get hold of information on how to write codes to communicate with the chip on a computer.
Anyone has any idea how/what I should search in order to start?

Just use an IR LED and a simple one transistor driver.
Try decompiling the apk in

sources/com/esmart/ir/IROTG.javaAnd the function
sendIRDataToExternalDevice

Thanks for taking a look at the apk.
Yeah I was looking into that just now and saw that method too. Will try to figure out how to replicate it in maybe a simple app.
This is what you are looking for:

Thanks, but how do you know is this chip?
Because obvious marking.
Ahhh 552 on the chip! How did I missed that
Thanks for pointing that out
