A real help about Feather 32u4

[Tarek]

Hello Everyone

We have a project using the Feather 32u4 BLE chip to communicate with an IONIC Application on Android.

And the huge problem is that i'm really really NEWBIE on this domain, i followed a sample tutorial on the adafruit website about sending data on Bluetooth but using their own application.

So can anyone help us to program the Feather so it can be on mode SLAVE, means that the BLE Module will be just listening on the information sent by our application.

What i want is to pair the Feather 32u4 with a smartphone using an application build on IONIC, and send data from the smartphone application to the Device

Hi Tarek,

I would suggest you to direct your question to Adafruit forum. You should be able to get better answer from them.

What I can suggest you is to try the example on the tutorial. As I can see they provide AT commands that you can use for your generic purpose.

Also there is DFU feature on the the BLE module. You may think of ignoring the Atmega chip on the board, and use the NRF51 directly via the DFU feature. Then you can use our library and SDK on the nRF51 on the module. It's may not be the best for development as it take much longer to program a firmware compare to flashing using a programmer. And you would need to prepare the DFU package and put it on the phone.
