I have followed the instructions on the Ruu.vi/setup and got started using my Ruuvi as a proximity bluetooth beacon, but after doing various tests all day I have come to the conclusion that the accurate range of the broadcast is only around 30m!
Now, the reason I expected more from the Ruuvi was beacuse of the superior antenna you guys stated on your website that it had and the 'range video on youtube’ - which showed a user’s device still broadcasting eddystone url 500m away!
So, my question is (judging that it’s even possible!) how can I increase the range? Are there additonal settings I must employ to ‘open’ the Ruuvi’s potential up? What;s this “untuned antenna” that is referreed to in the YouTube description box?
Anyway, my Ruuvi wasn’t indoors when I did these tests, I placed it outside (open air) and still only got 30m! Very frustrating to say the least!
My configuration settings on ‘nRF Beacon for Eddystone’ are:
Ad. interval: 300ms (also I’ll add this here, would 100 or 10 or even 1ms be a better setting, as I want to broadcast as fast as possible? If so what would that do to the device and battery etc?)
Radio Tx Power: 4dBm
There is also an additional Adv. Tx Power setting which allows you increase the broadcasting power to 20dBM - not too sure if this helps or not though as I have not seen even the slightest increase in range from using this and the 4dBm power levels - both are still broadcasting up to 30m. Which I think is crazy ridiculous.
Also, when I use my ‘Beacon Scanner’ app and emply the higher dBm settings I get the device showing me on the left hand side…
Distance and underneath crazy numbers like 22000m! Is this telling me how far I can broadcast or what? It totally confuses me!
Anway sorry for the long winded post and thank you for reading it.
