Arduino BLE Nano v2 Hardware Communications Question

[trwolfgang]

So I've been searching around for an answer to this on these forums and I can't really find what I'm looking for.

I'm using a RedBear BLE Nano v2 to act as an intermediate between an Arduino Uno and an Android App. I'm using the nRF5_SDK v15 libraries, and the arm-none-eabi-gcc compiler in combination with the s132 softdevice (via srec_cat) to generate the .hex files, which I'm uploading via DAPLink. 

This is all done from an Ubuntu 16.04 environment.

I've built most of my project off of the ble_app_template, and I've implemented a custom GATT profile to broadcast the data I want to send to my phone. All of that works fine.

My issue is trying to load data from the Arduino onto the RedBear chip, my Arduino is currently emitting U-ART messages on hardware lines, and I just want to read these messages from hardwired pins on the RedBear and update my Gatt profiles characteristics.

My question is what method/libraries/examples could I use to read from the Arduino via hardware pins on the RedBear.

You mentioned you are using SDK v15. I assume you are not using libraries from Redbearlab and can run our example directly. 

 

If it's the case, you can simply use our UART library to communicate with your Arduino. Check the \SDKv15\examples\peripheral\uart project.
