Sašo Domadenik has been tracking down an odd analog problem on the Seeed Studio forum: the ADC on the XIAO nRF54L15 picks up spikes whenever Bluetooth Low Energy is active. Sampling at 14-bit resolution with 128x oversampling, the readings jump by up to 10 LSB with the gain set to 2x. With BLE off…
