Silent crash
Just built on RPi. Make all worked fine in both librf24/rpi and examples/rpi_master. Launching rpi_master (sudo ./rpi_master) resulted in an immediate silent crash.
My hardware works fine with the regular RF24 library (have a working example from that library, but interested in using your mesh network with a RPi master).
Put some debug messages in, and seeing that GenericStation gets instantiated twice, and immediately after the second time, the virtual ~GenericStation executes and the app crashes. G++ version issue or something?
Hey Thomas.
I never had this problem, but to be honest I didn't used it on RPi for a while, maybe some update crashed some of my code? I don't know.
I will try to dig into this on the weekend.
Thanks.
Great, thanks!

The G++ version that my RPi has is: g++ (Debian 4.6.3-8+rpi1) 4.6.3
Which one are u using? Have u enabled SPI? "sudo gpio load spi"?
I also have 4.6.3. I have definitely enabled SPI. I've had working RF24 builds with other libraries. Looking to use yours because of the mesh features.

I take that back. The command sudo gpio load api doesn't work. I must be using a different method. I'll check into this and get back to you.

Take a look at: https://projects.drogon.net/raspberry-pi/wiringpi/the-gpio-utility/ http://wiringpi.com/
If I record correctly this is what I'm using to access GPIO/SPI
Yup. Installing now.

Okay, GPIO is intalled and SPI is loaded, and I'm getting the same problem.
I'm noticing that GenericStation gets instantiated twice, immediately, and then one gets destroyed, and there's a SIGTERM when the second one is attempting to destroy immediately after. It crashes in less than a second.

That is odd. I just recloned this repo in my RPi and compiled /examples/rpi_master with make.
And executed with sudo ./rpi_master and it didn't crash.
Have u done any change to the source codes? What is your RPI version?
I have added some printf statements, but it was crashing before I added those. I can start from scratch and try again.
I'll send a stack trace after I try it.

Tried an experiment. Swapped in Stanley Seow's RF24 lib for the contents of librf24/rpi, and it no longer crashes on launch. Can't tell that it's actually working, but it's not crashing.

I'm trying to reproduce it. It is kind of hard.
Can you list 'files'/permissions inside /sys/class/gpio? Could you try some debug inside librf24/rpi/gpio.cpp on method open. Print port and ddr and stuff.
What RPi are you using? I'm using the first released version.
How do I print port and ddr?
I have a rev B Pi.

Take a look into https://github.com/x-warrior/RF24SH/blob/master/librf24/rpi/gpio.cpp
port and ddr are params to GPIO::open, just print it as any other debug message.
No, I'm on a deadline, so I've had to go another route. I hope to come to this, though. Your DNS server-like features are definitely on my roadmap.

Please keep me posted. If I find anything else I will let you know.
If you have any question or need any other help, please let me know.
I set up a mesh of Arduinos (3) with the Arduino master and station examples to see how long you have to wait when adding each node. Can that time (seemed like 60-120 seconds) be optimized?
