5. AT Commands

User manual and hex codes for AT Commands supporting Bluetooth 5 features can be downloaded from

AT

Command Hex Codes, Bluetooth 5

section of this web page.

AT commands can be used on UART interface and SPI interface. Advantage of SPI interface is higher speed
data rate. A battery power product can complete data transmission sooner and go back to sleep mode.
