Is it possible to broadcast and to observe with nRF51422 simultaneously?

[holly]

Hi,

my task is to develop a "repeater" and I have three nRF51422 evaluation kits. For example, one of them sends a file, the second one receives it and then sends it to the third module. So, the one in the middle have to work as an broadcaster and observers at the same time. My question is: Is this possible and if so, how do I start?

I am still at the beginning and have only tried a few examples. Hopefully, this task is not too difficult for a beginner.

Thanks for your help and greetings from Germany

You might want to take a look at github.com/.../nRF51-multi-role-conn-observer-advertiser for some inspiration.

Hello Holly

Yes, your "repeater" is a common practice to extend the RF range. I am using "repeaters" in my application too.

Are you using ANT?

nRF51422 can have 8 independent channels existing at the same time managed by ANT SoC. It is kind of time slotting and much more than that. Plus, softdevice developed by Nordic gives you another time slot based way to use the RF for your proprietary protocol too, of course when Soc is not using the RF.

So, ANT, you can use one channel to receive the file and one channel to send the file as if you have one separate receiver and one separate sender.

Thank you both! It really helped.

I don't use ANT, but maybe I should. If it does not work, then I try ANT.
