Bleno with Raspberry Pi 3 Model B+ not working very well but Model B works fine #372

Hello,

We have both Raspberry PI 3 Model B and B+. When comparison between the two devices. Our software will work just fine on the Model B+ which uses WIFI and Bluetooth. When we install our software with Model B+ the Bluetooth will not work as the same as the Model B.

What I have found out is that on the Model B+ I can see the device show up on our application that is connecting/listening for. When connected it will send a few bytes and also let the device know that it is still online (ping/pong).

However on our LOGS shows that it does not receive a App Ping from the mobile app (iOS). When connected it will then try to get a list of wifi networks from the actual RPI which does show. However it crashes our mobile application. Bluetooth remains stuck, and the only way I can actually reset it completely is by rebooting the PI.

Basically commands like hciconfig hci0 reset or hciconfig hci0 down/up will result connection timeout issues. Nothing I do will not cause it to work.

Is there something that I need to know about to make this work? With Model B+. I do noticed that when we we're using Bluetooth Dongle at one time it would cause/do the same thing we're seeing again.

I have no clue where to go from here. Any help will be much appreciated.

Thank you, Ben

For anyone who may have the same issue. Update your raspberry pi 3 B+ to the latest kernel, nodejs 8.11 (at least) and download/use bleno 0.5.0+ which somehow is what fixed my issue.
