Function Documentation

GNSS_send_cmd_get_response()

uint8_t GNSS_send_cmd_get_response	(	const char *	cmd_buf,
		uint8_t	cmd_buf_len,
		uint8_t	rx_buf[],
		const uint16_t	rx_buf_max_size,
		uint16_t *	rx_buf_len_dest )

Sends a log command to the GNSS, and receives the response.

Parameters

cmd_buf	log command string to send to the GNSS.
cmd_buf_len	Exact length of the log command string.
rx_buf	Buffer to store the response (not necessarily null terminated).
rx_buf_max_size	Maximum length of the response buffer.
rx_buf_len_dest	Pointer to place to store the length of the response buffer (not necessarily null terminated).

Returns

0 on success, >0 if error.
