    Einstein here just bought a variety of Bluetooth relay boards to test for a customer project, which I am pretty sure use Bluetooth SPP and not BLE, then remembered something about B4i/iOS not supporting SPP. Did forum search, can't find any mention of definite progress in this area, but I did find these posts which gave me some hope.

    Firstly is this post and the following:
    Secondly is this post regarding a query to Apple about using Bluetooth:
    in which Apple's reply to Filippo says:
    which suggests that iOS supports (some?) standard Bluetooth profiles.

    Thirdly is this post about using AsyncStreams:
    where the following post has some sample inline Objective C (? I think) but the surrounding discussion suggests incomplete success.

    Has anybody successfully used B4i to communicate with Bluetooth SPP devices, eg, relay boards or ELM327? And if so, how?

    Hi @emexes ,

    I only use BLE since then, it is much easier and for me it is quite enough.

    I also recently used BLE for Android, and now I can use my Bluetooth device for Android and iOS. :)
