nrf52832 record noise

PCB above my collection of audio data by codec, and then through the Bluetooth upload, the audio signal noise will be ticking ticking, may I ask what is the reason

nrf52832作为主设备，codec作为从设备，当蓝牙的射频功能开启时，codec采集到的音频数据会有嗒嗒嗒的声音，但是当蓝牙的射频功能关闭时codec采集到的音频数据却没有嗒嗒嗒的声音。 Nrf52832 as the main equipment, as the codec from the device, when the RF Bluetooth is turned on, the audio data collected by codec will have despair of singing voice, but the audio data when the RF Bluetooth function closes codec collected without clacked voice

What is the name of the audio codec you are using?
