Hi,

Here, I encountered an initialization error with the C1001 60GHz mmWave sensor when using it with the Arduino MKR WiFi 1010 and ESP-WROOM-32, the output and code in below.

serial monitor output:

========================

init error!!!

Initialization successful

Start switching work mode

error!!!

error!!!

error!!!

error!!!

error!!!

Code:
