I'm designing a product which incorporates a magnetic sensor (MMC5633) and a Bluetooth microcontroller (NRF52832). The sensor and bluetooth chip share the same ground plane and LDO regulated supply. The dimensions of the board will be around 6 cm square. The sensor is measured at 100hz.
My question is, will the bluetooth radio interfere with the magnetic sensor? Based on what I've read about magnetic sensors from several manufacturers, these sensors should be positioned away from magnetized metals and from ferromagnetic materials as well as large inductors and long, high current traces.
I have a suspicion that because the bluetooth radio is operating at a very high frequency compared to the "slow moving" magnetic field that is measured by the sensor, the radio should not interfere with the sensor. Can anyone point me in the right direction? Thanks!
