ESP32 Custom PCB Issue

we build prototype using two ESP32 Wrover B and function of one module was to read all digital or analog data then send it to second ESP32 Module where we used 3 MAX31865 Modules and 1 MAX31855 module. Function of other module was to receive data and perform actions related to data. Prototype was sucessful so we moved to PCB designing.

In PCB designing we took referance design of all modules and ESP32 Wrover B but we cant able to measure any data on one microcontroller and other one is also not working.

Hi,

Can you be more specific about the "not working"?

First We are trying to Work with First ESP module and tried to read temperature using MAX31865 but SPI lines are not reading anything same problem with MAX31855 and other sensors.
