I’m using the HMC10 bluetooth with UART interface along with my STM32F103 board. Now I’m trying to make it work with interrupt mode, however, as there’s another sensor MPU6050 taking up a lot of CPU time to read/write I2C interface to get YawPitchRoll data also using interrupt, the UART interrupt can not reach a high data rate. So I need to change it to DMA mode, which I have no idea to make it work right now. I will figure it out tomorrow.
