5240 SDK V14.2.0 Bluetooth reconnect failure

[davidb]

I have a BT app on an IPad. I can connect to the the 52840 dev board  fine. I tell the iPad app to disconnect and it does.

nRF52840 dev board disconnects. When I try to connect to the dev board from the iPad app again the connection fails to complete.

I don't see BLE_GAP_EVT_CONN_PARAM_UPDATE event message during the second connection attempt.

I also don't see AMT_EVT_NOTIF_ENABLED type of message.

I don't know BT so debugging this is a bit new to me.

Thanks.

Hi,

When I try to connect to the dev board from the iPad app again the connection fails to complete.

1) Does the nRF52840 advertise when you try to connect the second time?

2) Do you see the same issue with nRF Connect app? https://www.nordicsemi.com/Products/Development-tools/nrf-connect-for-mobile

Any errors code when you try to connect?

3) 

I don't see BLE_GAP_EVT_CONN_PARAM_UPDATE event message during the second connection attempt.

Do you get BLE_GAP_EVT_CONNECTED ?
