Hi ,
I don't know if it is related to the code below?
#define UART_TX_BUF_SIZE 256 /**< UART TX buffer size. */
I cut two pictures and hope to help understand the problem.
I don't understand how the 0x04 framing error happened.
In addition, the baud rate used by UARTE is 250K.
Whether this transmission will affect Bluetooth?
Thanks
