Since this question is quite for long time, I suppose that you got the answer already, if not, please contact us (jc@iecont.com) for more information, since we had succeed to develop the app inventor code to contact the Nordic BLE devices, such as power plug, LEDs, Button, Buzzer, and temperature ....

Hi Tobi! I’m currently working on a project using nRF51422 and I would like to interface it with App Inventor… Did you manage to send data from nRF8001 to App Inventor?? I have more doubts in the code part of NRf51422. Could you help me please?

thank you a lot. Took me some time to get that there is indeed a small different in the service and characteristic UUID, haha. Just have the problem that all variables i send get changed. If I send a byte, it gets multiplied by 1000, and int/string get 48 added. (when i read it with the serial monitor). A bit weird, but I guess it's an app-inventor or RedBearLab issue (I use parts of the simpleControls sketch). Just saying, maybe someone here knows about it;)

@Tobi: You can find the UUID by using our nRF Master Control Panel app. You can download the app from Google play or Play Store. Your question is similar to this. And by following it you can find this

I meant UUID;)

Hey, thank you. How do I get the serviceUIID/characteristicUIID? I'm using one of the RedBearLab Arduino-examples, and it looks quite simple wherefore I wanna try it with this first.

github.com/.../SimpleControls.ino

There is no UIID definied in this sketch. How can it communicate with the suitable app?

I know about your Tutorials here, but they are not about Arduino and I think it should be possible to get that without extra software and hardware, shouldn't it?

@Tobi: If your app can interface with BLE, it should be able to interface with the nRF8001. You just need to make sure your connect to the right device, write/read/enable notification with the right characteristic/service (the UUID).

Note that the BLE chip on the Adruino 101 may not be the nRF8001, we don't know which chip is inside that Curie module. But it doesn't matter as BLE is a standard and your app should work with any BLE chip.
