commit 7354ab187ed701ae041b45a0a6603878ab9b165d and commit 1e2f06718103e7028809012a69b7ac932e9ae537 added code to skip all remaining channels when the channel number is -1. This adds support for testing that using the example app. The BL602 driver's first channel is channel 0, so this also allows the example app to select the first channel.
