Phil's lockdown project - a 4ch propo NRF24 set

[WernerL]

As far as I know the epoxy-blob ones are XN297 (Chinese company Panchip http://www.panchip.com/products_135/220.html).
This chip has some extra commands and is therefore not 100% software compatible with the nRF24.
Have a look at https://github.com/pascallanger/DIY-Mul ... tiprotocol where you can find code for both nRF24 and XN297.

As for the nRF24L01+ vs non-plus: nowadays one certainly want to use the + version. Nordic may not even make the non-plus version any more.

From the Nordic datasheet:

Intermodulation and wideband blocking values in nRF24L01+ are much
improved in comparison to the nRF24L01 and the addition of internal filtering to nRF24L01+ has improved
the margins for meeting RF regulatory standards.

cheers, Werner

Edit (Phil_G): this hybrid-hopping project is obsolete now, its been superseded by the full FHSS version.
The full FHSS system has been built & flown regularly by many members over the last 4 years, and whilst development continues, in its current state its a good solid project that works very well.
