The receiver code enables the receiving Arduino to receive data from the nRF24L01+ chip and process that data. Because the analog-to-digital converters (ADC) have a resolution of 10 bits and the 'normal' analogWrite function only has a resolution of 8 bits the data values need to be remapped.
The Test Code. The following bits of code can be used to initially test your NRF24L01 module in a new circuit. Hence one piece of code is for sending data while the other receives data. Furthermore the receiving data has a counter to make it easy to check for dropped packets when testing the wireless transceiver at different ranges.

Mar 15, 2016 · [Arduino] NRF24L01+ modules testing. With a group of friends we decided to explore the wireless side of arduino.Searching a bit on google we found a nice and really cheap 2.4GHZ module, the NRF24L01+ module for about 2.60 euros a couple (what the heck do you need just one for?).

Jun 23, 2016 · Libraries are files written in C or C++ (.c, .cpp) which provide your sketches with extra functionality (e.g. the ability to control an LED matrix, or read an encoder, GSM, GPS, NRF24L01 etc.). Arduino software is kept flexible users can create there own library or add libraries for new devices.
I'm using the NRF24L01+PA+LNA radio modules to create a mesh network of inexpensive, identical nodes. There is zero topology configuration, and the network should map itself. Maximum (rated) range between modules is 1km (with 250kbps) and 2mbps at 250m. The total cost of a solar-powered RF unit is currently (estimated) $16. The mesh should implement TCP/IP communication. Communication should ...

I've just uploaded the Java codes for the rf24, rf24Network and rf24Mesh that work with Android Things.This time I didn't write a library because I thought it was better to upload an Android project that can be opened with Android Studio (>2.2.3) and directly started on the Raspberry Pi.
