ESP32 based Bluetooth adaptor?
« on: Thu, 25 February 2021, 17:50:01 »
Hello, Hope everyone is doing alright during the craziness of pandemics.

I'm trying to make a Bluetooth adaptor for my Model F. Directly decoding XT protocol and to the Bluetooth, since I want to use my Model F on my lap in my sofa :thumb:
First, I found I can use cheap hc-05 and override its firmware to make it HID-compatible. Unfortunately, it seems many of HC-05, especially recent ones, are using relabeled old BC3 chipset, which is
not compatible with HID firmware--mine was too ( check this thread https://github.com/lorf/csr-spi-ftdi/issues/25). Since HC-05 is no longer an option, I was wondering around and found ESP32, which is a powerful iot controller that supports Bluetooth HID, yet I never seen anyone utilizing ESP32 for their keyboard.
Is it a good idea to use Bluetooth HID controller with ESP32 stand alone? I'm aware it's not compatible with USB-HID, but I'm okay with that. If you have any experience with ESP32, how long is its typical
battery time?

Thanks!
