// Set tChannel(108) // 2.508 Ghz - Above most Wifi Channels.Set tDataRate(RF24_250KBPS) //Fast enough.Like this: tPALevel(RF24_PA_MAX) Or try intermediate settings first: RF24_PA_MIN, RF24_PA_LOW, RF24_PA_HIGH and RF24_PA_MAX **After** you have **good** 3.3V power, set the RF "Power Amplifier Level" to MAX.You can use a separate 3.3V supply, or a Base Module powered from 5V that has a 3.3V regulator, or a YourDuino RoboRED. Make sure you have good 3.3V power (not just plain UNO, Mega etc.You can do these things to get better range: The example with tPALevel(RF24_PA_LOW) will be only 10 feet or so. Indoors the range will be less due to walls etc. This is for open spaaaaaace between units operating at a Data Rate of 250KHz. The usual distance quoted by different suppliers for the low-power version module with the single chip is 200 Feet or 100 Meters. Range is very dependent on the situation and is much more with clear line of sight outdoors than indoors with effects of walls and materials. NRF24L01 SOFTWARE AND LIBRARIES: (Jump Ahead IF you're ready for that.) Range Newer boards like the ] have 350 ma or more available and can run even the high-power modules directly. that has only 50 ma of 3.3V power available. These instability problems are particularly noticeable when 3.3V power comes from a UNO, MEGA, Nano etc. See the schematic of the base board shown on the right on as an example. 1uf and 10uf capacitors close to the GND and 3.3V pins. If you design a printed circuit board that the module plugs into, add.They make it easier to get started and keep operation reliable. These have a 3.3V regulator built in, AND good power bypass capacitors. But the easiest and best solution is low-cost base module like this: (RIGHT) that you can plug nRF24L01 modules into.Use aArduino UNO compatible, which has an added 3.3V regulator (But add a.For testing try powering the nRF24 with a pair of AA alkaline cells (3v) with the battery GND connected to the Arduino GND. Or you are using the regular Arduino UNO which provides only 50 mA at 3.3V
