build up centra-peripheral multi board BLE system

[StefXinet]

Hello everybody,
I have to develop an embedded system to acquire and process data. I will be using 2 custom PCBs based on nRF52832:
1- Sensor board: very low power consumption, it acquires data from a sensor and will transmit the data in raw format via BLE.
2- Processing board: it connects to board 1, processes the data and communicates the results to a smartphone.

I defined 2 different bluetooth profiles: the first is used to communicate the data from the sensor board to the processing board; the second profile is used by the smartphone to set settings and read the data processed by the processing board.

I need some help on how to properly configure the GAP of the two PCBs with nRF52. I made two hypotheses but not only what is the best and if they are achievable.

this is the fist idea:

and this is the second:

Please could you help me?

Hi again

I understand, that makes sense! We have a few example projects that covers multirole applications in our SDK. Depending on what exactly you're looking I would suggest checking out either the BLE Relay example or the LE Secure Connections Multirole example.

Best regards,

Simon

Thanks for your help.

we saw both example you suggested but unfortunatly the documentation is not sufficient to understand how to modify the examples in order to adapt them to our application. in the Nordic documentation it is indicated only how to program and switch on the DK, this is very simple but not enough to understand how to use your libraries.
we also studied the documentation of "Nordic UART Service Client" and "Bluetooth low energy central tutorial", they are confusing.

Could you suggest us some clearer documentation? Is there any documentation that we haven't found?
