Unable to reconnect after disconnection in Samsung Devices.

[amitsanvedi]

Hello Team,

We are using nrf52832 device and SDK version 12.2 Softdevice3.1 to program our watch device.

We have iOS & Android native application to communicate and data/transfer with this watch device. All is working fine except disconnection in Samsung device. After the disconnection (due to out of range or Bluetooth turn off/on)it is not able to reconnect back. It works fine with iOS and other Non-Samsung device.

I believe most of the people encountered this problem, so please let me know what's wrong with Samsung Devices.

If you need further details, please let me know as it is getting more critical day by day.

Regards,

Amit

It is for all Samsung devices like S5/S6/S7 etc and all the OS version like 5/6/7 etc.

I don't have sniffer trace at the moment, I will download this app and try to get it for you ASAP.

Great, let me know when you have a sniffer trace.

If you are working on your own app, please see the doucment(BLE_on_Android_v1.0.1.pdf) in this blog post on what to keep in mind when developing your BLE Android app. Especially the chapter on the autoConnect parameter (page 8) might be of interest to you.
