FMRadio.seekUp()

Summary

The seekUp method is used to tell the radio to seek up to the next radio channel. The search circles back to lower frequencies when the highest frequency has been reached.

If the frequency is successfully changed, the frequencychange event is triggered.

Only one seek is allowed at a time: If the radio is already seeking when seekUp is called the request will fail.

Syntax

var request = instanceOfFMRadio.seekUp();

Returns
