I am using STM32WBA5MMGH6TR in my project for sending data received from a sensor. BT is used for transmission.

The data will be transmitted to a central node.

This is a battery operated device. The signal chain is given below.

Sensor--> ADC-->STM32WBA5MMGH6TR.

Could you please review the attached schematic.

That's just a crystal - not an external oscillator.

A complex system that works is invariably found to have evolved from a simple system that worked.A complex system designed from scratch never works and cannot be patched up to make it work.
