Getting two NRF52832 to send strings/data with each other

[destiny98]

Hi there, I am new to working with UART. I have managed to load the Nordic UART Service Client(Central) and UART Serial  Port Emulation(Peripheral) without any sensors attached to it. I am trying to understand how to send data or strings between both of them. I have tried to reference materials online and someone connected the two boards with wires, but I want it to be transmitted wirelessly so that it is not the way i think. Am I suppose to send them via the serial port with the RTT viewer where there is the enter part, tried sending strings but does not work. I do not know how to use the serial port or where to access it too.

Hi, 

You can use these two examples: UART/Serial Port Emulation over BLE and Nordic UART Service Client to sent data in UART to each other. Please read that documentation about setting the test.

Hi Amanda, I do not understand this part from the Nordic UART Service Client:

6.Now it is possible to send data between the two boards. To do so, send data to one of the boards using the serial port. Observe that the data is displayed on the UART on the other board.

How do I test this part?

Hi, 

1. Connect the board to the computer using a USB cable. The board is assigned a COM port, which is visible in the Device Manager.
2. Start a terminal emulator like PuTTY and connect to the used COM port with the following UART settings:
   • Baud rate: 115.200
   • 8 data bits
   • 1 stop bit
   • No parity
   • HW flow control: None

Yes I have already done this for the peripheral side. I am having trouble with the central side instead. I want to learn how to do testing on the central side instead of using the nRFConnect app to send strings/data. The intention is to be able to test to send data/string when implementing long range with UART.

Hi, 

It is the same procedure as you did for the peripheral side. You need to open two windows of the terminal emulator like PuTTY, one for the peripheral, another one for the central.

Got it to work. Thank you Amanda!
