Hi,
My product is automagically disconnected from the central after 9min of connection...
The same problem can be reproduced from the ble_app_template example as is, on a NRFDK. The device is disconnected from the central after 9min too.
The disconnection appear only when the peripheral is bonded with the central.
Central configuration:
- Phone: Wiko Rainbow with Android 4.4.2
- NrfConnect
Peripheral configuration:
- NRFDK PCA10040 v1.1.0
- Softdevice s132_nrf52_6.0.0_softdevice.hex
- NRF SDK 15
- Sources : unmodified ble_app_template from sdk examples
Steps to reproduce:
- Both mobile and peripheral are clean (device completely erased & flashed and everything is clear on the BLE side of the mobile phone)
- From NrfConnect bond the device to the mobile phone
- Connect to the device and do nothing else than waiting 9 minutes
- The peripheral should be disconnected from the central with reason 0x08 / BLE_HCI_CONNECTION_TIMEOUT (BLE_GAP_EVT_DISCONNECTED)
Any help will be appreciated to understand why the link is automagically disconnected after 9min when the peripheral is bonded and connected to the mobile phone.
Regards.
