I have a query with respect to the parameters of the operation

wiced_bool_t wiced_bt_spp_send_session_data( uint16_t handle, uint8_t * p_data, uint32_t len )

within the BTSDK v3.2.

The documentation states:

'The first 2 octets of the p_data must be the handle passed to the application in the wiced_bt_spp_connection_up_callback in the big endian format.'

However I see in the RFCOMM_serial_comm example project with spp.c in the operation

void app_send_data(void)

The  data buffer passed to the wiced_bt_spp_send_session_data operation does not contain the handle.

I have a project based on the RFCOMM_serial_comm example project which does not add the handle to the first octets of the data being sent and all works well.

It seems odd that wiced_bt_spp_send_session_data has the handle as the first parameter yet the handle also needs adding to the data buffer.

I'd like an answer to:

Why does the documentation for wiced_bt_spp_send_session_data state the SPP handle should be the first two octets of the data buffer being sent, yet in the RFCOMM_Serial_comm example this is not done and the code works with out these first two octets being the SPP handle?

Thanks.

The document should be updated and the handle is not needed in the p_data part.
