Decodes ble_l2cap_evt_rx event.
If p_event is null, the required length of p_event is returned in p_event_len.
- Parameters
-
| [in] | p_buf | Pointer to the beginning of an event packet. |
| [in] | packet_len | Length (in bytes) of the event packet. |
| [in,out] | p_event | Pointer to a ble_evt_t buffer where the decoded event will be stored. If NULL, required length will be returned in p_event_len. |
| [in,out] | p_event_len | in: Size (in bytes) of p_event buffer. out: Length of decoded contents of p_event. |
- Return values
-
| NRF_SUCCESS | Decoding success. |
| NRF_ERROR_NULL | Decoding failure. NULL pointer supplied. |
| NRF_ERROR_INVALID_LENGTH | Decoding failure. Incorrect buffer length. |
| NRF_ERROR_DATA_SIZE | Decoding failure. Length of p_event is too small to hold decoded event. |
