Let’s develop a simple chat program so that we can chat without the internet ! :p The algorithm that i m going to use is as follows...... ON THE TX NODE – The program waits for a serial input. As soon as the user enters the input it stores it in a variable until the …

Exploring the Auto-ack feature of the transceiver

Please go to the post whose link is provided after this paragraph and do not try to implement the codes provided here. The link will take you to my latest post where this feature has been explored properly. Although there is no theory on what Ack payload is so you can read the theory part …

Writing your own code

We will transmit integers and strings here to get some experience and fluency in writing our own codes. The trick to write any code with minimum or no errors is to first draw a detailed flowchart or algorithm that you will follow. I know it's trivial but believe me people who are new to programming …

Understanding the codes in the library

Now we will try to understand the coding techniques of maniacbug and how the same code runs one transceiver in TX mode and the other in RX mode. Lets start with the Getting started code. First of all you write all the header files that will be needed for the working of the transceivers. Since …

Getting started with the transceivers

nRf24L01+ transceivers are really great wireless solutions owing to their ease of use and cost(I bought a pair for 380 rupees from e-bay). In this and the following posts i tell you how i proceeded with them ,the problems that i faced and the important things that you need to know before transmitting your first …
