How to connect 6 nrf52840 boards on a board as central and send data via serial UART?

[RicardoFranco]

Good afternoon.
I need to make a network 5 or 6 nrf52840 boards connected as peripherals on a single central board, also of nrf52840.
Each board will read a sensor, and send the data by BLE to the central.
The data received by the exchange will be passed through the standard USB UART that appears on the PC when we plug the DK-52.
Where can I find software that does this?

Hi Ricardo,

I will recommend you to download our nRF5 SDK and start out taking a look at the UART/Serial port emulation over BLE example for peripheral devices here, and the for central devices, here. The examples are in the SDK folder under the following paths <InstallFolder>\examples\ble_peripheral\ble_app_uart for the peripheral devices and <InstallFolder>\examples\ble_central\ble_app_uart_c  for the central device.

Best Regards,

Marjeris

That will show you how to do one peripheral to the Central.

Once you have got familiar with that, and got it  working, look at the Multi-link example for how to get the Central to support multiple peripherals simultaneously.

Hi msromero,

I tried to do this, but i can't communicate using a simple terminal.

Hi awneil,

I need an example that does this:

Yes - that is exactly what Marjeris Romero and I described.
