Fun Game project : 2.4 Ghz RF / nRF24LU1 feasability ?

[Guillaume]

Hi, we would like to create a kind of game using 2.4Ghz emitters . The 2.4Ghz USB Dongle emits and the mobile phone detects the frequency + embed unique ID/code so we confirm if the person has been there ;-). No cheating !

Attached is our concept so we would thank you if someone can confirm we have chosen the right hardware before to buy.

Many many thanks ! Giom

I see that you write in your document that this has to work with both WiFi and BLE off, and this is simply not possible, at least not through the regular APIs that iOS exposes to applications.

However, if you can live with requiring Bluetooth to be on, the project should be doable with Bluetooth low energy based tags, for example employing our nRF51822.

Your concept looks interesting, but one thing to verify is whether a standard mobile phone can directly detect the custom 2.4 GHz transmissions from the nRF24LU1, since most phones don't natively support that protocol. It may require an additional bridge or compatible receiver. Aside from that, using unique IDs to prevent cheating is a solid idea. If you're interested in seeing how game communities share features and improvements, you can also explore the latest updates on The Spike through this fan resource, which many players have found useful.

I came across this discussion and found the idea of using 2.4GHz RF emitters with unique IDs for a game project quite interesting. For anyone exploring mobile gaming concepts and related projects, I noticed a website that offers interesting content around a popular mobile gaming experience. You can learn more by clicking here. It may be helpful for people interested in game ideas and digital entertainment projects while comparing different approaches and possibilities. The website’s content looks impressive and worth checking for those who enjoy discovering new gaming resources and creative project inspirations online. It can provide useful ideas.

<a href="">www-cricfy.in/">cricfy app</a> is a mobile-friendly platform for cricket enthusiasts who want to follow match-related information conveniently. Depending on the available version, it may provide scores, fixtures, schedules, team details, and other cricket updates in an easy-to-use interface. Users should verify the source and review app permissions before installation.

This sounds like an interesting concept. The nRF24LU1+ seems well suited to a small wireless game prototype because it combines a 2.4 GHz transceiver with USB and an onboard microcontroller. Nordic also lists game controllers and toys among its potential applications.

For the phone side, I’d make sure the device can reliably identify the transmitted code rather than simply detecting the 2.4 GHz signal, since the band is shared by many wireless devices. A simple unique ID plus packet validation would make the “no cheating” idea much more reliable.

It would be interesting to see this applied to modern mobile gaming too. For example, download this if you want to explore another mobile gaming experience while thinking about how wireless hardware could interact with games.
