14.4.2Interface Description

This command is used to set the QoS of fix request, include the performance and the accuracy threshold. READ command queries current QoS, TEST command returns supported QoS range. SET command can only be used before position session beginning or after end, can‟t be used during positioning, or will be error.

Notes: the command is not supported when operation mode is Cell-ID.

14.4.3Parameter Description

<performance>: the level of desired performance in the scale of 0 to 255, this value encodes the preferred response quality(in seconds) to be used for the GPS pseudorange measurements. No storing at power down.

0: this indicates that no time is to be spent making GPS measurements

1 to 255: this indicates the upper bound for GPS search. Note that this does not correspond to overall session time, but only the amount of time spent searching in GPS mode.

<accuracy>: this allows applications to specify(in meters) the accuracy threshold for a GPS fix. The range is 25 to 1000 meters, default value is 50 meters, no storing at power down

<err>: error code or error description

Error code	Error description
4	Operation not supported
