nRF24L01 p Channels

[rfengr]

I'm trying some testing on this chip.
Basically this new chip allows you to turn on the carrier frequency (unmodulated) .

So I'm trying to sweep the unmodulated carrier frequency from Channel=0 to Channel=128, and I'm observing the output on a spectrum analyzer.

The chip successfully sweeps the first 30 chosen channels (2.430GHz), but must be reset to choose another 30 channels.

Anyone experienced this before ?

Thanks ..

Hi

This question about the Nordic VLSI part is a little "off topic" as this is a CCS compiler forum.

The nRF24L01 is a excellent part but you must remember it has a major limitation in that the TX runs open loop. It is intended for very short bursts of data, in the order of 1mS and the high data rate of the part is achieved by opening the PLL during transmission. This allows the free running VCO to be directly modulated, so avoiding all the normal problems with modulating phase locked oscillators.

This may be why you are having problems.
