ESP32H2 Hardware Design, Matter Communication Error

[ethan1111]

Dear experts, I have two questions. Please help me, thank you.

I don't know how to add images, I'm sorry.

I use ESP32h2 to implement matter communication. ESP32h2 comes with a shielding cover, and when only using the smallest system of ESP32h2, it can achieve matter connection and control;

However, when the esp32h2 minimum system approaches the metal, it will not be able to communicate with the material and will prompt:
E (1267) OPENTHREAD: Failed to send to Thread netif: packet queue full
E (1267) OPENTHREAD: Failed to send to Thread netif: packet queue full
E (1277) OPENTHREAD: Failed to send to Thread netif: packet queue full
E (1277) OPENTHREAD: Failed to send to Thread netif: packet queue full
E (1287) OPENTHREAD: Failed to send to Thread netif: packet queue full
When the minimum system board of ESP32h2 is close to the transformer, the communication function of the inductor and other components will also fail, and the prompt will be the same as above。

My ESP32h2 small card needs to be connected to a switch power board. The ESP32h2 I purchased comes with a shielding cover. What should I do to solve this problem?

There is another question, ADC sampling. When IO3 is grounded, will the read ADC value still be 860?
And, I am unable to register for software calibration：
esp32h2的esp_adc say：
//Now no scheme supported
#pragma once

/**
* @file adc_cali_schemes.h
*
* @brief Supported calibration schemes
*/

//Now no scheme supported
