I’m trying to see if it would be possible to use ESP32 to emulate the BT remote for my TV box to toggle the power. I have found the BT address for my TV from the Android device settings but I’m assuming that’s just for pairing BT devices to it.
My next question is how to figure out the power toggle BLE signal being sent from the remote?
Reverse engineering the data is really the only way. Analyse the data.
@nickrout thanks for your response! If possible, could you give me some pointers or an idea of resources to check in order to reverse engineer this perhaps? I have just recently purchased an ESP32 CP2102 dev board but I haven’t even set it up yet. Literally my first time messing with any of this.
I have the BT remote, so I guess how can I first start reading the data being sent when the power button is pressed?
