RAIL Syncword

Hello,

 

When I setup a RAIL Radio Configuration I can set the Sync Word (actually two of them). But is there also a way to set the Sync Word later on at runtime as well?

Hi Marteen,

 

You can reconfigure the radio any time in idle state. You should generate the new config ( the "generated[] array in rail_config.c) with different syncword in a separate project, and copy and use the new config in your original project.

Hello @tanagy

 

With the syncword set to 32 bit and the requirement to let the user specify the "wireless address" this means I have to generate 2^32 configurations of 512 bytes each and store them somewhere in the flash of the FlexGecko. I hope you understand this is not going to work for me.

Hi Maarten,

 

If you diff two config arrays, you will see you don't have to store the whole array.

A hint: you can also load partial configs, just keep full lines and the 0xFFFFFFFFUL, at the end.
