I’m measuring a small noise signal radiating from the Mangoh red with a WP7702 module in the range of 64KHz. Since we are using this module in a project where we need a very sensitive 55KHz receiver, this signal is disturbing our signal. I suspect it may be a second harmonic of the 32.768KHz sleep clock.
Is there a way to disable the 32KHz sleep clock? That would make it easy to solve or rule it out.
