The sample also requires a phone or tablet running a compatible application. The Testing instructions refer to nRF Connect for Mobile, but similar applications (for example, nRF Toolbox) can be used as well. You can also test the application with the Bluetooth: Central UART sample. See the documentation for that sample for detailed instructions. Peripheral usage for nRF52¶ Some resources are available for direct access if special low level access is required. Others are available via specific APIs or used internally by Mira OS. To use the peripherals of nRF52 directly, refer to the corresponding nRF52 product specification for information.

Carbon Dioxide modules such as MH-Z14A, MH-Z19B (and maybe some more) are supported on Ardunino / ESP8266. Both output signal modes UART via Serial Port and PWM are suppported. See example and/or manual for wireing the mhz14a or mhz19b. Downloads The nRF5 SDK is a high quality, thoroughly tested software development kit to accelerate your software development efforts for the nRF52 and nRF51 Series SoCs. It contains hundreds of useful firmware modules and examples to assist in building your application.

By default, the app_uart_fifo is based on the legacy uart driver which can support both nRF51 and nRF52. It gets one byte on every time (imply that the DMA length = 1). By using the app_uart_fifo driver, it would get challenge on higher baud rate during the BLE link is established.

  19. The Nordic nRF52832 microcontroller on the RAK8212 board only has one hardware UART, which is many cases (like this case) is used to create a serial connection with components on the BG96 module. For this reason, you should not interface with the RAK8212 board using a serial connection over the USB cable, because if you do, your serial connection will go away as soon as the nRF52’s (single) UART is switched to establish this board-internal serial communication.
