oref0-setup: Using the ShareBLE CGM mode with a G4 receiver doesn't work

[jaylagorio]

I've been able to get oref0-setup to work on an Edison using a G4 receiver when the receiver is connected via USB OTG but have not been able to make it work using the ShareBLE option. The Bluetooth stack gets installed and appears to be working because Bluetooth tethering to a phone works properly. After that even simple openaps commands fail, all the same way:

root@tinyaps:~/openaps# openaps use cgm ReadSystemTime

In /root/src/openxshare/openxshare/ble/uart.py, in __init__(), execution doesn't get past self._uart = device.find_service(self.UART_SERVICE_UUID).

@jaylagorio : it would be nice if this will be fixed and that openxshareble does not depend on bluetooth. Have you used the EXTRA option dexusb on oref0-setup.sh? That will install my python script which works with USB OTG. Unfortunately I get a lot of problems with the USB device on my explorer board with a European Dexcom share, so I'm still stuck on a raspberry pi 3 rig.

I think this is is a openxshareble issue and should be reported there. There are other known issues, see openaps/openxshareble#5

@PieterGit I haven't seen anything about EXTRA or what dexusb is. I'm using a US device and using USB OTG haven't found any problems. I didn't realize shareble had a different repo, thanks for pointing me that way. I think that issue is the same as or related to this issue. I'll close this issue and point to it in a comment over there.
