how can we generate a continuous waveform to measure the output power on a custom board using STM32WLE5CCU6.



We are designing ou custom Lora application based on the STM32WLE5CCU6 MCU.

1- We would like to know if there is an eval board that can be used in manufacturing tests to perform a pingpong communication test (between our custom board and the eval board). Is there an AN that decribes such test ?

What we ve found is this document that can be used to perform a ping pong test.

Are there any other related documents ?

For the eval board we ve found two boards:

The later one do not have any mention to the STM32WLE5CCU6 MCU (Only STM32WL5)

Which eval board should be used ?

2- Is it possible to generate a continuous waveform from the STM32WLE5CCU6 MCU in order to make frequency and power measurements ?

hello @Kimmel1​ and welcome to st community .

For your first question, you should use the stm32wl55jc card to perform your tests . For the ping pong application and point to point application , i suggest you take a look on this ping pong , P2P application and this video .

For your second question, you can use the MCO (microcontroller clock output) that allows you to output the clock for external MCO pin ( you can also use LSCO for the LSI and LSE clocks) . for more details, take a look to the ref man. And for the power measurements take a look on this training.
