How do I find out the sourcd code of NRF_RADIO.

[imc_user1]

I am reading up some open source bluetooth stack implementation with NRF51822 with the objective to understanding the Bluetooth firmware.

My prior knowledge are baseband, modulation and PHY. And I program Arduino, HC-05 BT libraries and know the AT commands well. I will like read up the knowledge in-between. 

I notice there are quite some references to NRF_RADIO, for example NRF_RADIO->PACKETPTR, NRF_RADIO->FREQUENCY etc. 

Where can I find the source code for this structure? 

If the source is not open, where can I get some documentation on this library?

After some digging I realize it could just be the data structure containing the register table in section 16.2 on page 83 of nRF51_RM_V2.1.pdf.

Am I right?

Are there any sample codes which use the SOC as a generic GFSK or DPSK transceiver without any existing standard? I create a simple protocol.

Hi,

 

You would probably want to use both the nRF51 Production Specification (PS) and Reference manual (RM) to accompany your understanding of the code examples, as these documents describe the SoC and modules inside. SW documentation is found in the Documentation Ibrary, SDKs both have sections documenting the examples and the individual libraries or drivers. I recommend looking at radio transmitter and receiver examples or the enhanced shockburst (ESB) examples in the SDK.

 

Best regards,

Andreas
