Questions about SparkFun Pro nRF52840 Mini

Wireless & IoT Bluetooth
1

Hello,

I was looking to buy the SparkFun Pro nRF52840 Mini to use in a project but I`m unsure if it will be able to accommodate my needs.

My Questions are:

-Is it able to act as a Client in the communication with another BLE server device? In other words can it be a observer (in the GAP) and connect with a broadcaster. Then in the GAT can it act as a client and subscribe to a Notifications request.

-Is it only capable of using standard public UUIDs or is it possible to program and use Private UUIDs with private services?

  • Just a confirmation because by the information on the site it looks like it can. But can i connect it to another microcontroler via serial and receive the information it’s getting via Bluetooth? And also control the communication?

Thanks for the Help!

I suggest looking at the central examples in the nRF52840 Arduino board package and libraries.

https://github.com/adafruit/Adafruit_nR … es/Central

The hardware examples includes at least one that uses Serial1 (hardware UART).
