Nordic nRF51822 UART Service Solution (Module: MDBT40)



UART service, as known as NUS (Nordic UART Service) is the most common and easy way for BLE relating IoT Implement.
Customers who is familiar with Classic Bluetooth are used to call as SPP service.

Raytac Module MDBT40 series, build by Nordic nRF51822 solution, has been widely applied in IoT based on UART service to help developers obtian a low entry barrier and time to market efficiency .

Although UART is a quick and easy access to build up the BLE products, we would like to provide some kind reminding listed in below for all developers. 
  1. Packet size: 20 byte
  2. Interval: Suggested set as 50m Sec
  3. For Data <400 byte/sec (baud rate set as 9600), there is no need to support flow control function
  4. For Data>400 byte/sec (baud rate>9600, says as 19200 or 115200), we are strongly suggest to check if MCU support flow control function to avoid data loss.
