nRF8002 and RFduino

[alexgluc]

Hi,

I'm planning to use a nRF8002 to transmit via BT the state of a pushbutton to a RFduino. I've my RFduino ready to receive data (and this works when paired to my iPhone - tested through its own app). I've then tried to link the nRF8002 and configure that via nRFgo Studio. I've been reading that with a nRF8002 I can use the Alert Notification or Immediate Alert on the peer to transmit the button press to the peer. In this case the nRF8002 should act as a GATT Client but I don't really understand how to set that out through nRFgo Studio. Even when the nRF8002 is running in the configuration I've set (output leds blinking), I can't find it among the BT devices around me and in the command line tool it seems that my nRF8002 only receives something when I press the button connected as input1 but fails to transmit that external input it has just received.

I'm a BT newbie and any suggestion/link I can use to get more about configuring properly the nRF8002 via nRFgo Studio for my case is kindly appreciated.

Thank you for your help.

Yes. I am talking about the "Demonstrate running the command line tool" in the tab "Upload configuration" of nRFgo Studio. I should be able to see a transmission activity and not only "RX", shouldn't I?

I am wondering whether I have got other ways than the "Demonstrate running the command line tool" in the tab "Upload configuration" while using nRFgo Studio to real-time monitor the activity of my nRF8002 bluetooth tag. As with a serial monitor I would like to see whether the tag transmits data on air, for instance at the press of a pushbutton connected as input to the tag itself. I haven't been able to see such an activity on the pop-up window from the "command line tool" even when the tag is paired to my iPhone and ready to communicate with it through the nRF Proximity app.

Any help is very much appreciated! Thank you in advance.

I see your problem, the command line tool is intended to do production programming of your nRF8002 configuration. It is not a test tool. It takes the configuration that you have created in studio and sends to to the nRF8002 so there is no need for the nRFgo studio once the configuration has been created. In short, you are using the wrong tool.

You have a number of ways to demonstrate the nRF8002 to see what is transmitted. The simplest ones are to use existing apps like the lightblue or the Android master control panel for BTLE. You use these apps to setup the nRF8002 Services over BTLE. This should allow you to use all the GATT Service functionality. However it may be more difficult to use the nRF8002 GATT Client functionality.

The more complete way would be to use the Nordic Master control panel and the proximity demo PC application that is available when you purchase the nRF8002 Development kit. This requires a master emulator dongle that is shipped with that development kit.

Additionally if you have acess to a BTLE sniffer you can see the air packets as they get sent from the nRF8002 to the app on the phone.

I hope this answers your question.
