A&D Device

I have a 1100BLE. It works well on the first run however, blessed keeps scanning and reconnects after removing the device from the blacklist. This blocks all subsequent operation i.e I can't read data from the device.

If I am to take measurement from the device before blessed reconnects all works fine. If the device sit idle and bless reconnects to the device I can't take measurement from the device. I have tried central.stopScan(); but the device does not send notification after the first run.

The device automatically disconnect once it send data to blessed I guess this makes blessed to reconnect. Any pointer on how to make blessed not reconnect and continue listening for notification will be appreciated.

Hi, I have never used the 1100BLE so I am not familiar with it. However, feel free to experiment with the demo app to make it work for the 1100BLE. It is just a demo app and not the Blessed library.

Can you share logs so I can see what is going on? In particular for the second connect that doesn't work.

What I have noticed is when doing setNotify in onServicesDiscovered the queue/signal thread to the device hangs in my debugger. If I introduce time delay to set notification for the device characteristics all works fine.
