Sensor data via BLE with Arduino IDE with Redbear Nano v2 dev kit

[siddhartha]

Could you please help me out on how to read my EMG sensor values and display it via the Nrf tool box. I have a redbear nano v2 and the digital output of the sensor is received on the pin number D3 p3_0. I wish to transmit the voltage readings on to the nrf toobox to look at the number. I am working on arduino IDE as Keil doesnt integrate with the readbear IDE.

PS I can send serial data via this code by changing the UUIDS of the Nordic uart service,
Please suggest a code if possible

Hello,

I am not familiar with Arduino's nRF implementation. But if you are able to write to the characteristic, then that is a good start.

How do you read from the sensor? You mention voltage, so I assume that you can use something from this project to read the voltage:

Best regards,

The EMG sensor emits analog signals which is connected to the ADC pin , and I need to transmit these values via ble on the NRF toolbox application.

Ok. It looks like the example that I linked to in the previous post is reading analogue signals from a pin. You can try that, and see if you can get some values. If that works, you can try to add the part of the code that reads the analogue pin and use the values from this in the project that you have found, and pass the values into the NUS service.

 

Best regards,
