Model: Park10 J3-CUB

If a CC2500 is installed it will be used for this sub protocol. Option in this case is used for fine frequency tuning like any CC2500 protocols so check the [Frequency Tuning page](/docs/Frequency_Tuning.md).
|
||||
|
||||
If only a NRF24L01 is installed then this sub protocol might be problematic because it is using the xn297L emulation with a transmission speed of 250kbps which doesn't work very well with every NRF24L01, this is an hardware issue with the authenticity and accuracy of the components.
