pyBlufi

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.

Why

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.

MTU

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.

Requirements
