Send data from one nrf52 to another nrf52

[Reza papi]

Hello everyone. I am trying to develop a communication link between two nrf52 devices. I want to collect measurements from some sensors, pack them into a single data pack and send them every for example 10 seconds and receive the data on the other board and finally send the data with UART peripheral. The main reason to wish this service is to save power as much as possible. do you have any suggestions? at this stage, I create a gatts service with a notification that can update the data on nrf app on my phone every 5 seconds.

Thank you

Hi

Adding sensor data in your advertising dataand scan response data as long as there aren't too many bytes. This does of course require that the scanning device is continuously scanning, or else I would recommend a connection instead I think where the device could go to sleep between transmissions. Have you checked out the Online Power Profiler on DevZone which can give you a few estimates on what current consumption to expect during advertising versus connections and so on?

Best regards,

Simon

Hi

yes I checked the online profiler and it seems with connection interval in some seconds I can reduce the power consumption. do you have any suggestions or example in the sdk based on the requirements of my project?

Best,
