NOTE: This is a WIP. Feel free to clone and try it out, but not installable with pip yet.

Python utility to interface with esp32 Blufi component. Mimics EspBlufiForAndroid and EspBlufiForiOS.

Useful for testing/debugging Blufi commands without having to use a phone. Thus making it easier to implement new features, build on top of Blufi and not having to design apps and protocols from scratch.

On some platforms, negotiated MTU is not accessible via API. On Linux, bluez does not provide a way (yet?) to get negotiated MTU via dbus. For this reason, payloads must be artificially capped using the setPostPackageLengthLimit method. Using setPostPackageLengthLimit(256) should work in most cases. If the client PC has a requirement for lower MTU, then this must be set lower. Or if/when bleak can correctly obtain MTU for a given platform, it can be removed.

As far as MTUs > 256:

1. ESP-IDF defaults to 256, but can be configured to use up to 512.

2. The ESP-IDF Blufi protocol is limited to 256 bytes. You could likely modify it if you wanted to, and maybe it could still work with MTU negotiation but I have not put much thought into it.
