void platform_interface_callback	(	uint8_t *	data,
		uint32_t	len
	)

the callback to upper layers to process received packets

This function is implemented by the upper layers (the event loop) and it is up to the platform implementation to call it whenever data are received from the interface

Parameters

[in]	data	data received from the interface
[in]	len	length of data

at_ble_status_t platform_interface_send	(	uint8_t *	data,
		uint32_t	len
	)

sends a message over the platform-specific bus

Sends a message over the platform-specific bus that might be UART, SPI or other if the BTLC1000 external wakeup signal is used, it is up to this function implementation to assert/deassert it appropriately

Parameters

[in]	data	data to send over the interface
[in]	len	length of data

Returns

Zero if operation completed successfully

Non zero for Generic error.
