UART Service (NUS) is the most convenient and common Bluetooth Lower Energy proprietary service for all developers.
Raytac has introduced NUS (UART) BT4.2 and BT5 solution in previous article.
nRF52 series SoC has below features rather than nRF51
1. nRF52 supports Longer Package MTU
(500 Bytes for Baudrate 9600 / over 10K for 115200 or 230400)
2. nRF 52 has over 10 times higher transmission speed than nRF51
3. nRF52 only needs 1/10 (or less) transmission time than nRF51
Raytac has been hearing from developers about the demand of AT command over UART service based on Nordic Solution.
Learnt from customers’ feedback, Raytac realized that Long Package MTU is the recent critical demand for all customers and IoT applications.
As such, Raytac hardware team has selected Nordic nRF52810 solution , powered by firmware design team to develop a coming AT Command Over UART Service Solution.
The features of the AT Command Over UART solution not only brings a cost effective module, but an easy and user familiar method enables an easy and time-to-market efficiency.

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.
