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

A beacon generally is an advertising device that does not connect to a central device but just advertises data in 31 byte advertising packets and alternatively a scan response packet of the same size. Please note that this is not very secure compared to connecting to a central device and bonding to encrypt the connection before transmitting data, as any BLE scanning device will be able to detect and read this data. Will security be a high concern for you?

Best regards,

Simon

I prefer to be to be secured but as I said the main concern is power and sending just my data not something like uuid or rssi or...
