nRF52 example code to transmit periodically

[paul_tanner]

I have a sensor device that needs to transmit every so many seconds. I am looking for a code example to run on nRF52-DK that will do this, sleeping inbetween transmissions. Any suggestions pls?

For clarity, I want to use a phone app to receive the data. This will forward it to the cloud if it has a connection or cache it until it does.

Hi Paul
Do you have any protocol requirements? Or put another way, will the sensor talk to a phone or tablet (necessitating the BLE protocol), or will you use nRF52 devices in both ends?

I would start with the "ble_app_uart" example project in the SDK which will take care of the transmitting part.

Since its sensor device you will probably need the ADC, you can look at the "saadc" example in the SDK

And for timing you can take a look at the "simple_timer" example.

By combining these you can achieve what you need without too much difficulty.
