Original question:

CC2640: CC2640 RF

CC2640: CC2640

Part Number: CC2640

Cc2640 is classified as smart BLE it also IOT  by advertisement. So we ran custom app with 2640 to simple link app on IPhone. We were able adversities/discover but we could not see data on the cloud.

We ran a test using the launchpad 2650 push button and we have data transmission on simple link app.

Why isn’t 2640 transmitting on the cloud w/ simple link?

    Are you sure your custom application on 2640 does transmit the data to simplelink starter app first? If you run simple_peripheral example on your custom CC2640, does it work?

    Thank you YK,

    simple_peripheral example does work on my custom board w/ cc2640 transmitting to on laptop GUI. 

    I've researched that the 2640 can be configured for IOT based on many TI articles i've read dating back to 2015.

    My question is what is stopping my 2640 from transmitting to simple link app on my iPhone. my board advertises with the simple link app but app is not receiving data from board to the cloud.

    You said "board advertises with the simple link app but app is not receiving data from board to the cloud. ". Does Simplelink starter app can connect to your CC2640 running your own BLE application? If so, it's possible that  Simplelink starter app cannot get your GATT characteristics. If this it the case, I think you need to write your own smartphone app or change your GATT characteristics to use those in simple_peripheral example to make it work.
