Hello,

I have STM32-WBA55CG connect with MEMS sensor. STM32 board will send the messages back to terminal through USART. The WBA55CG is right now connected to stationary power source. It would be nice if someone can give some ideas, how to transform it into a mobile device and save USART messages?

Hello,

I have STM32-WBA55CG connect with MEMS sensor. STM32 board will send the MEMS values back to terminal through USART. The MEMS sensor should be mobile in order to get values and i'm stuck at finding solutions to save the USART messages from STM32.

If you are looking for more storage (more than flash available storage), you may think about using an external memory (SD card through SPI for example) to store the data.

The only nonvolatile storage available on the chip is via FLASH. Dedicate a page of flash for storage and use that.
