BLE STACK EVENTS : BLE_OTS_L2CAP_EVT_CH_DISCONNECTED.

[[email protected]]

I am working on developing BLE app using connection oriented channel . I am using nordic semiconductor as a peripheral device and iPhone 6 as central manager. 

I am able to connect to the device and open L2CAP channel.I am using Object transfer service.  But its getting disconnected.  Below is output of debugger (Nordic nRF52) : 

<info> app: Peer Disconnected.

<info> app: Peer Connected.

<info> ble_ots_l2cap: Accepted L2CAP Channel

<info> ble_ots_oacp: BLE_OTS_L2CAP_EVT_CH_CONNECTED.

<info> ble_ots_oacp: BLE_OTS_L2CAP_EVT_CH_DISCONNECTED.

<info> app: Peer Disconnected.

what could be the possible reasons ? Could you please let me know how to proceed I am stuck at this part.

Thank you.

Hello,

Can you enable debug log level so that we can see a bit more of the log? :)

It looks like it is the peer/iOS that chooses to disconnect. We have never tested the object transfer service against iphone as far as I know. So there could be plenty of reasons.

What SDK version are you working with?
