nRF24AP1 ANT+ Continuous scanning mode

[rahmat]

Hi, I am using nRF24AP1 for ANT+ purposes and I am looking for continuous scanning mode (the radio is active in receive mode 100%). The command Open Rx Scan Channel (0x5B) seems to do just that but is not available to nRF24AP1 chip. Is there another way to do it? I was thinking to Open the channel with Open Channel (0x4B) command and Request Message (0x4D) in an infinite loop.

Thanks, Rahmat

That is not possible, please consider look at the nRF52832, this is a system on chip solution where you can also run your own application with ANT and/or BLE:

Alternatively you may consider the nRF24AP2-8CH if you want to use your own external MCU.

Thanks for the answer, I am aware of that. It is just that I need to measure power when it is completely RX mode, (for certification purposes). Further looking, I also found that nRf24AP1 also does not have background scanning, all I have left is normal search mode. That is the only thing closest to complete RX mode unless you have other suggestion?

For the nRF24AP1 that is correct, have in mind the chip was the first ANT enabled chip about 14years old, so I strongly suggest to consider the nRF24AP2-8CH instead.
