s130 disconnection after 1 min

[gigatronik]

hy,

i am using s130 as a central device. I can establish a connection and also read the characteristics. I also enabled notifacation for one characteristic. Everything is working fine but after 1 min the connection is lost. The reason i get on the callback for disconnection is BLE_HCI_REMOTE_USER_TERMINATED_CONNECTION.

Does that mean that my central device disconnects or is the peripheral disconnecting? What could be a reason for disconnection?

Hi gigatronik,

On which device did you get the BLE_HCI_REMOTE_USER_TERMINATED_CONNECTION disconnect reason ?

Which device your S130 connect to ? Do you have the same problem when testing with our S130 example ( central and peripheral)

hi hung bui,

i got the disconnection reason on my s130(central). I am connected to a nrf8001(peripheral). it seems that the nrf8001 is requesting an update of the connection parameters and my centraldevice does not response. So the connection is lost.. What should i do next?

@gigatronik: You can either modify the application firmware for the nRF8001, or just accept and reply to the connection parameter update request from the nRF8001 on the S130 side. Please have a look at our ble_app_hrs_c in the SDK, we handle the BLE_GAP_EVT_CONN_PARAM_UPDATE_REQUEST event in on_ble_evt() in main.c.
