Hi Martin,
Welcome to the seeed community:)
May I ask what product you purchased specifically? Because we have 2 products based on MR60BHA2:
The sole sensor: 60GHz mmWave Radar Module - Respiratory Heartbeat Detection | FMCW | Sync Sense | Privacy Protect - Seeed Studio
And the sensor module with MCU: XIAO 60GHz mmWave Human Breathing and Heartbeat Sensor -MR60BHA2
For the former product (the sole sensor one), it’s life has ‘ended’ so we do not offer any technicial support. For the later, could you please attach any photo of the error raised? Also, please offer me any GUI code you tried to execute?
Regards,
John
