[Ovmsdev] Bluetooth struggle

Sat Mar 28 04:22:55 HKT 2020

Chris,

sorry for the outdated bluetooth sdkconfig and lack of info on this.

The bluetooth component development was done by Mark. It's been stopped at an early stage without usable functionality IIRC. It was supposed to pair, but
nothing else. It used up a lot of memory we needed for other tasks, and there was no real need for this, so we excluded it from the standard build.

It's been stuck there since mid 2018, and the IDF API may have changed in the meantime. I think the IDF even introduced a whole new driver approach later on, so
the component may need a complete rewrite.

You're welcome to work on that, but maybe there are better options for what you'd like to do, or you can work with a simplified approach.

If I understood you correctly, you would like to access the UpMiiGo's main CAN bus via a bluetooth OBD2 dongle, because the main CAN isn't available at your
preferred OVMS mounting point.

My own experiences with bluetooth OBD2 dongles were all bad, very slow and unreliable, unsuitable for live CAN data. That's been years ago, maybe the situation
has changed, but I still would prefer a cable, also because I don't trust these cheap bluetooth (or wifi) devices to be secure. Isn't the CAN bus reachable
somewhere near?

Regards,
Michael
