Bluetooth support for Raspberry Pi Zero W


Please forgive me if this question is a bit incoherent, I’m a bit of an IoT/Particle/Raspberry Pi noob.

I’ve got my Raspberry Pi Zero W working well with Particle, including some i2c stuff. So far, so good.

Next, I want to port over some bluetooth code I had running in Python, but I was working at such a high abstraction in Python that I’m not sure if/how bluetooth might be supported via Particle.

In a nutshell, what I’d like to do is port this library, that supports controlling BLE outlet, over to particle:

Suggestions on where I should start? Is there a low level bluetooth library already ported to particle that will work with my Raspberry Pi Zero W?

Thanks in advance for any pointers

So, it appears the simple way to handle this is to create an rfcomm channel and then open it like a serial port. However, from what I’ve read and seen Serial1/2/3/4 doesn’t actually work on the Raspberry Pi. I also read that a work around would be to drop down to wiringSerial, but I can’t seem to include that from the web IDE.

Any suggestions?

For now, as a workaround, I’ve just hacked it further to directly open /dev/rfcomm :frowning:

I’d be interested in seeing your hack. Can you share how you did this?

I just googled on how to use rfcomm and then with some trial and error I made it work by just reading/writing to an rfcomm device. I no longer have the code, because in the end I decided to just ditch the bluetooth stuff - it was slow and not super reliable. Instead, I just use a relay wired directly to my pi.
