BTLE failing to start with string error #1

Open hirsts opened 7 years ago

hirsts commented 7 years ago

Hardware = RPi3 with DWA-171 I have been testing with Qubie and gone through the install process many times with different combinations and options and cannot not resolve BTLE not working. When Qubie starts it calls the btle service

qubie.log:

[2017-01-27 17:11:20 EST]: started btle service

Wifi is running fine and below is "ps -ef" of the failed process:

root      1172  1115  0 Jan27 pts/0    00:00:00 [qubie_btle] <defunct>

The following error is from qubie.err:

 buffer.js:750
        return this.hexWrite(string, offset, length);
                    ^

I will take a look when I can; it appears to be an issue with Bleno, but it could also be that Bleno used to correct for some mistake the Qubie code is making and no longer does. Thanks for letting us know!
