X-NUCLEO-BNRG2A1 Resistor mapping

Pgonz.1

Bluetooth development is a new field for me so I would like to start without any doubt.

I'm checking the X­-NUCLEO­-BNRG2A1 for learning and using BLE in another project.

My question is about the register mapping on the datasheet of this board. Why are these not mounted and when do I have to mount which resistor or make a shortcut?

Is there any document with this information or any guideline?

Thank you.

I see that there are notes like "To use PA1 as SPI_CS with DIO1 mount resistor R70". But I don't know the value, do I have to calculate it? or is there a fixed value somewhere in the manual that I'm not seeing?

The purpose is to use a module like the BlueNRG-M2SP or similar in my project. And to have the ability to program the BLE of my PCB, for that I guess I need the values of these resistors? Any help in this field is useful! Thank you

They are being used as jumpers. A 0 Ohm resistor will work.
