How much additional range can be achieved using the high power nRF24L01+ data transceiver?
And some interesting results with data timing.

My understanding is the board with the large antenna has a LNA and a PA, the other does not. You should have used the board with larger antenna as the receiver i.e. left it in the shop. The one without larger antenna should be outside (as the transmitter). Of course, the test should have used two boards both with the larger antennas. Thank you very much for doing these reviews!
i guess the receiver gets overloaded(excuse my layman statement please). i also used the delay(50) in the loop and it started receiving correct data 🙂
i highly doubt the high powered transmitter was underpowered, i read somewhere that the antenna one needs about 200mA and the arduino can't supply that amount, so maybe thats the problem idk ;-;
hey can u provide the code please….
Not bad for being through a wall and still having a weak receiver.
can i get the code for both aurdinos
with that amplified transceiver I made it out 1 km, receiver on a 3 story windowsill
do you still have the code for this? thanks
Hi, have you ever tried to use a Mega with theese modules? I'am having problems with it, with no clue of what the problem is…
Thanks for the video. I was having the exact problem you display with my project. Works 100% at PA_MIN and near 100% fail at higher power levels. My NRF2401 module is supplied with its own power from a regulated supply and I have added a 47uf capacitor across the pins with no change to performance. However by chance, I discovered that if I cup my hand over my circuit board with the, antenna poking out ,as a shield from the antenna, my high power performance goes to 100%. I can watch the change in performance change as I move my hand on and off the board. This suggests to me that RF is getting into the circuit at higher power levels disrupting the radio. I plan to add a shielded box around my circuit board (a Faraday cage of sorts) with the antenna poking out the side. I hope this may work for others. 73s de KJ6FO
I suggest you to use high power nRF modules on both ends with a delay of 75 milliseconds. I hope that would be fine…
I think I agree with others that have suggested these units, being 2 way may be communicating with each other and the signal still suffers from having to wait for the lesser powered transceiver.
Instead of the delay, why not just put a sanity check in to ignore the failed packets/connection. I would be interested in seeing how many successful packets are transferred, ignoring the failed data, compared to the original transceiver.
Also, I have a couple different antennas for video transmission and have found that there is often a big difference if I switch these out on the transmitting and receiving sides. Maybe it was more reliable because the original antennae were more similar originally? It looks like the range is definitely being extended though, even with only one side being upgraded.
can you share the arduino sketch for NRF24L01+??
