Hi everyone,
As many others I have started up a Drone project. For communication I've chosen the high power NRF24L01+ PA+LNA. Bought them from Ebay and have probably spent 10+ hours now trying to get them work properly without to much packet loss.

I have added 10uF capacitors between GND + VCC. Separated power supply. But still have tons of random issues. Sometimes the RoundTrip example in ManiacBugs RF24-lib works, sometimes it doesn't.
When I looked closer to the board itself I found something interesting, its probably defective. Some pins are soldered together on the 2401C (see attached picture).
So now I need your help, can this be the issue? I have tried to find the datasheet and schematics of the board itself without success.
Hi,
The pins soldered together are probably to allow for current flow and also to help with any heat dissipation.
If you use the Search box in the top RH corner of this page and search NRF2401.
I have some of these low power versions, but haven't had a chance to play with them yet.
Have you tried the example sketches that come with the Library?
Can you please post a copy of your circuit, in CAD or a picture of a hand drawn circuit in jpg, png?
Can you please post a copy of your sketch, using code tags?

The defect that you have noticed could be due to poor soldering, or it may be purposely done as an attempt to rectify a bad design.
Now that you have it documented, why don't you remove the excess solder. Then see whether the performance is improved, reduced, or remains the same.
If removing the solder makes the device perform worse, then you could reinstate the "defect".
I bought a new set of NRF24L01+. Now it works out all fine. Got these => http://www.elecfreaks.com/wiki/index.php?title=2.4G_Wireless_nRF24L01p_with_PA_and_LNA.
But at the same time I was learning and discovered a lot of possible code issues. So I am not sure that the first ones really where bad. But will probably not find out.
