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

Thank you for specifying your predicament.

AFAIK, there are no BLE services for IMU sensors, but it should not be too difficult to make a custom service that transfers IMU data for you. I found this guide at hackster.io where they explain how to set up a BLE service that transmits IMU data. If you follow our Custom Service Tutorial, available here on GitHub, and creates a similar BLE service from there, you should be able to transmit that to a central device that you have connected to your computer.

The easiest way to get this data onto your computer, I think would be to use the nRFConnect Bluetooth Low Energy app where you get a GUI of the nRF52 DK as a central that can scan and connect to peripheral devices. That way, the only coding necessary would be the implementation of the custom BLE service.

Best regards,

Simon

so should i still start by using one of your examples ?

[Simonr]

Indeed, try following the custom BLE service tutorial, and then modify the custom service to match the IMU sensor service.

Best regards,

i went through all the steps and in the last step it seems that my development board is no longer being found on the nrfconnect app, i  checked and I'm sure i followed them steps well
