SDK 14 migration

Hi again,

I have advertising up and runnnig and can connect to my server through the nrfConnect app. However after ~39-40 sec(every time) the connection is lost with errorcode 34(LMP timeout). And I can read all my characteristics.

MAX/MIN_CONN_INTERVAL and CONN_SUP_TIMEOUT are the same as in SDK12.

MIN_CONN_INTERVAL MSEC_TO_UNITS( 10, UNIT_1_25_MS)
MAX_CONN_INTERVAL MSEC_TO_UNITS(500, UNIT_1_25_MS)
SLAVE_LATENCY 0 CONN_SUP_TIMEOUT MSEC_TO_UNITS(1000, UNIT_1_25_MS)

I have a very good link RSSI at about -60-70 dBm. What it going on?

nrfConnect LOG says:

[Callback] connection state changed with status:34 and new state: DISCONNECTED(0)

[Server callback] connection state changed with status :0 and new state DISCONNECTED(0)

[Server] Device disconnected

Error 34(0x22):GATT CONN LMP TIMEOUT

Disconnected

[Broadcast] Action received:android.blueooth.device.action.ACL_DISCONNECTED

Best regards Bjarke
