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

i have similar example, send sensor data from nrf52832 to esp32 via BLE by changing uuid bytes in advertise message from iBeacon example. it is the most battery saving which i can found

great! what is esp32? and can you please share your code with me? 

[Dien Nguyen]

ESP32 is a type of Wifi & Bluetooth MCU. And here is my example https://github.com/dienvx1997bn/nRF52-SHT1x-read-and-adv-data. the UUID is a list of bytes contained in the advertise message, so the scanner can "see" it and decrypt data

Thank you very much, it's really kind of you. just one more question, what is the time between 2 consecutive advertisement?

it is defined by NON_CONNECTABLE_ADV_INTERVAL
