nRFPROG download

[Gustav]

Hi 

I still have a number of devices that are based on nRF24E1. From time to time the chips need a change in firmware. Since the last time I updated them, my PC has crashed, and I don't have the nRFprog anymore. 

Do you have a version I can download?

Best regards,

Gustav

Hi Gustav

nRF24E1?
Now we are talking, that part had been around for a while when I started in Nordic back in 2008

Good to hear you found the files.

It is still -to my knowledge- the only chip that have a simultaneous dual frequency receiver radio . That is ingenious because the likelihood of both frequencies fading at the same time is minimal.

Hi Gustav

You are correct, the duoceiver feature never carried over to later devices.

Modern RF protocols rely on channel switching instead to handle channel diversity, and the new radios have focused on reducing channel switch time rather than support reception on multiple frequencies at once.

Yea, "duoceiver" wonderful name. 

If you really focus on reducing channel switch time, then get it down to zero with the duoceiver. 

Please, duoceiver is all I want for Christmas. It is so much easier with duoceiver to write a protocol that is fairly stable. Just say you will think about it.

HI Gustav

This is the first time someone mentioned this feature in years, so I don't think it's something that is high on the radar anymore unfortunately ;)

Normally you are using channel diversity to get around interference from WiFI and similar sources, and in this case the 8 MHz channel spacing is a bit limiting. If you are hit by WiFI interference for instance then you can easily be blocked over a 20-40MHz band, and you want to use channels at the bottom and top of the band. 

I also have no idea how well this feature would work with our modern RF architectures. I am pretty sure that having to support duoceiver would have a negative impact on other aspects, such as current consumption, wideband blocking, sensitivity etc. 

The problem these days for cool proprietary features like this one is that more and more of our customers are using standard protocols like Bluetooth low energy, Thread or Zigbee, and the radios are optimized for this primarily.

Haha, now that would be some Christmas present!

I wish I could make promises like this, but that is what we have a sales department for. You would need to discuss requests like this with them ;)
