Hello,

While checking the sniffer traces, I can see an attribute not found error (in packet 4813). I guess this is because you are using a service or characteristic that isn't supported by Mac or Apple. Could you share the details of the service your peripheral is using?

One more reason could be that the peripheral insists on a MTU size that's larger than what Mac allows, so you can give a try by lowering the MTU size in your application (may be to 180; not sure on this number, but I guess Mac allows 185).

Kind Regards,

Abhijith

Hi Abhijith,

our application scans the near by devices and connects with one specific device by using system(PC(windows, linux or MAC)) Bluetooth module.
After that the system will receive the sensor data's from the peripheral device and soft reset (nvm reset) will happen
and then the device will trigger the disconnect.

We are using ublox nina-b302 module and nRF5 Software Development Kit v17.1.0

Error we got in terminal: Peripheral device disconnected: Error Domain=CBErrorDomain Code=6 "The connection has timed out unexpectedly." UserInfo={NSLocalizedDescription=The connection has timed out unexpectedly.}

Thanks in advance

Hello,

Could you share more details on this issue, like what sort of application you are implementing? You mentioned that an error occurs after the system reset. I hope you are referring to the development board reset here. Could you confirm this? Which SDK version and Nordic chip/board are you using here? The error you have shared is a general time-out error. Could you share the whole log? I will also recommend capturing the sniffer traces to get an idea of what's happening over the air.

Kind Regards,

Abhijith
