You are using RF24 library. I would recommend using the NRF24 library, that is what I used for my research. Its simple and easy to understand.

Which library are you using. I would recommend using the NRF24 library. Changing the air data rate is easy, just go through the examples given in the library.

A greater range would be achieved if you use 1Mbps or 256kbps air data rate.

Hi, it would be good to give details about the shield that you made.

Hello

Which library are you using in your program as there are a number of libraries available for nRF24L01+ radio modules.

Can someone please advise how to make the date and time library to work on Arduino 1.0.1 as it gives some bug when trying to compile.

Where to get the full datasheet.

Hello,

The following line is from the arduino website:
SPI: 10 (SS), 11 (MOSI), 12 (MISO), 13 (SCK). These pins support SPI communication, which, although provided by the underlying hardware, is not currently included in the Arduino language.

Does this mean the SPI pins do not work for Arduino Fio. I want to use the Arduino Fio with NRF24L01+ which requires SPI communication.

Can anyone please advise where I can get the datasheet for Arduino FIO

Here we are looking at not only 1 node, but many nodes hence when it comes to the fact of deploying many sensor nodes then the cost seems high.

But nice suggestion, definitely it will solve the problem where only few nodes are required.

I am doing my research under wireless sensor network and as such the cost and power consumption are very important. Therefore the only option could be replacing the resonators with crystal oscillators. Using a external clock would increase the cost and power consumption of the sensor nodes.

Found out from Arduino that Ceramic Resonators have been used on Arduino Mega 2560 R3.

The crystal has the following marking: SPK16.000G

Yes, I assume a resonator is used on the one I am using as I have taken one micro controller  as the ref and measured the skew and its gives me ppm error of upto 1000ppm.

I was trying to study the relation between the applied voltage and crystal skew. But it seems the board has resonator which is not very accurate. How can I solve this problem. My aim was to obtain less than 5ppm error with the arduino without using any external clock.

Hello

Does anyone know what is the tolerance of the crystal oscillator used in Arduino mega 2560.

Regards

I have checked and it is Arduino.h

Any idea what the problem can be. Still my mirf examples are not compiling.
