PTR5618-MS is a BLE module with a master-slave feature. The module is based on nRF52832 with an ARM Cortex-M4F processor from Nordic Semiconductor. Therefore, the PTR5618-MS features Bluetooth 5.0, high performance and ultra-low power(ULP). The user's MCU is connected to the module through a serial port (UART), so that it enables bidirectional communication of data with the mobile device. After receiving the data from the serial port of the user MCU, the module will automatically send it to the mobile device; The mobile device can write data to the module by the APP, and then the module sends the data it received to the user's MCU through the serial port.
