bluetooth transfer between 2 nrf

[NikTheNordicUser]

Hi , i would like to send some sensor data coming from SPI interface and then send it from one nrf52832dk onto another nrf52dk or a nrf52dongle and on the receiving end send the data serially to mathlab gui.

can this be done ? if so may someone guide me on how to do it please I am relatively new to nordic and would appriacte a bit more detail then just be pointed to the examples please.

thank you very much for your time

best regards nikolai dimech

Is it the Dongle or Development Kit that you can't see in the nRFConnect app any longer? Do you still see the Development Kit in your Device Manager as a JLink CDC UART Port? If not, have you maybe held down the reset button while powering it on at some point, putting it into the bootloader mode by mistake? If that's the case, please try reinstalling the Interface MCU firmware. It can be downloaded here, and you can see how to reinstall/update it properly on this page in the Infocenter. If it's the Dongle you can't find, please check out the Dongle Programming tutorial to see how you can recover it.

Or, are you referring to that you can't find the device as an advertising device any more when scanning with a central? If so, the advertising initialization or start is not implemented correctly most likely, and you should take another look at the advertising_init() and advertising_start() functions in your project.

HI , i took another approch where I used the ble_app_uart and I modified that and I am currently getting sensor data on the nordic uart app.

my next step is to connect two nordic devkits (nrf52dk) where instead the data is sent to the app it is set to the other nrf52dk any suggestions on how to do this please??

may you be more specific pls

I believe awneil is referring to the Nordic UART Service Client, available in our SDK, with documentation and test procedure available here.

do i need to put the UUIDs the same ?

[NikTheNordicUser]

and is there a way how i can visualise the transfer in order to confirm that the transfer has been made please

 I don't understand the question I'm afraid.

The ble_app_uart examples write data received over BLE to the connected computer over UART, so in order to have some kind of visual confirmation you can use a terminal to open the COM port and see the received data here. This is also described how to do in the setup on Infocenter.

Best regards,

for the client is it possible to do a uart function to transmit certain characters over ble back to the peripheral?
