Pocket Chip updated with Bluez 5.46 first try worked great!

I got my pocket chip in the mail this past week. And I’ve been curious if I had to do anything to my bluez 5.46-1 build working on chip

Pocket Chip comes with the original CHIP (not the pro). It has some spaces and breathing room to do a lot in 3.3GB (2.6G free) of space.

On to trying out bluez 5.46;  I just installed it and it worked out of the box.   https://github.com/eSpecialized/bluez-5.46-rpi3

Pocket Chip once updated is at version Debian 8.9.

Preliminary tests;
scan on = success
scan off = success

after reboot; still running
when I removed the bluetooth from within my paired iPhone and tried to start up bluetoothctl, bluetoothd was dead.

I power cycled the device, to ensure it is still running.
bluetoothd is back online.  And it all works great. This means the firmware is loading at boot time properly.
remove (iPhone Mac address) = success.
trust 64:A5:C3:B8:9A:2B:D6 = worked
pair 64:A5:C3:B8:9A:2B:D6 = worked

I’m all paired up with my iPhone again.

What benefits does this have?
I’ll get back to this. Today is looking like a beach day for my family.  Least to say BLE works really great in Bluez 5.46, plus numerous other bug fixes since 5.23.

My true plans are really to work with the BLE and see how well it works. Also to work with some A2DP with stereo headsets and play some mp3’s.

Trying PAN with Bluez 5.46
