BLE_NUS_C_EVT_NUS_TX_EVT has handle of 0xffff

[syc776]

I have following problem:

I am using a multilink NUS Central. With one peripheral connection everything works fine. But when make a second connection I sometimes get an error when I try to send data back in received event.

In ble_nus_c_evt_handler event with event type BLE_NUS_C_EVT_NUS_TX_EVT the p_ble_nus_c sometimes has an invalid connection handle (0xFFFF).

If I try to send data back I get following warning: <warning> ble_nus_c: Connection handle invalid.

How is this possible? I am assigning the handles with  ble_nus_c_handles_assign on discovery complete.

Does anyone know about this issue?
