Re: Unable to get Pi and Pi TNC to work with my Radio
¿ªÔÆÌåÓýHello Ryan,According to K4GBB excellent TNC-pi doc file, (), you certainly also changed boot parameters removing all reference to ttyAMA0 and console=tty1. dwc_otg.lpm_enable=0 root=/dev/mmcblk0p2 rootfstype=ext4

Using RPi to remote control a Baofeng UV5R or similar portable radio via Android
I'd like to use the RPi to remote control a Baofen UV5R or similar radio via an Android app. ?I'm only looking to receive and transmit, not change frequency or in any other way control the radio. I've searched the internet but have not been able to find anything on this subject. Has anyone done this or can point me in the right direction? I have some experience with RPi. ?I'm using one RPi for running a PBX and Fax in my home and another as a NAS for my media. |

Re: Unable to get Pi and Pi TNC to work with my Radio
¿ªÔÆÌåÓýHello Ryan,First of all check that you correctly inserted TNC-Pi jumpers J3 and J4 correctly and in the right way, that is parallel to GPIO 2X13 pins , not orthogonal i.e. jumpers must not join JP3 to JP4. If you still do not copy any AX.25 traffic on your screen with listen -a then check the following. First, you must configure TNC-Pi port in serial mode. In order to do that you must not load any AX.25 driver nor attach any driver to serial ports (no kissattach command). Did you edit /etc/default/ifplugd and replaced HOTPLUG_INTERFACES = "all" by "eth0" ? This should be done. Did you edit /etc/inittab and add a # sign in order to disable line starting with T0:23 Here is how it should look : #T0:23:respawn:/sbin/getty -L ttyAMA0 115200 vt100? Check TNC-Pi configuration using pitnc_getparams 0 0 or 1 0 depending on your revision board. Line 07 should display I2c address (0=async) 00 If parameter is not 0, set it to 0 for serial mode using command pitnc_setparams 0 0 7 0 or 1 0 7 0 (again depending on your TNC-Pi board). Check that configuration is ok using pitnc_getparams again. If you enter these command when a driver is already attached to serial port ttyAMA0 you get an error message saying : error while loading shared libraries : libax25.so.0: cannot open ...... In that case disable scripts that loaded AX.25 at boot time and reboot your Raspberry to configure it. ? I hope this could help you. 73 de Bernard, f6bvp Le 28/09/2014 22:53,

Re: New to raspberry pi
David, ? That's a pretty wide open question you ask.?? I'm using several Raspberry PIs in an attempt to build an over-the-radio wide-range VHF packet radio network.? In my application I put Raspian Wheezy Debian OS onto the PI.? I actually wrote a primer for people trying to start from scratch for my use of the PI and you might want to read what I say to start out, even if you are going in an entirely different direction.? It will give you some idea how to start. ? See this document I'd say stop at the point where I talk about "Running the TARPN install scripts" because from then on it is pretty much just about making a packet node out of the PI.? Before that is somewhat generic.? Some of the choices I make are not necessarily what you'll want and you can keep those things in mind or make your own choices. Since the PI runs off a memory card you can have multiple boot images and mess around with it knowing that nothing you do is irrevocable.? Feel free to ask any questions or to correct my grammar etc! .? I've only been using the PI since January so I'm somewhat new to this as well.? ?? Tadd On Oct 01, 2014, at 12:12 PM, "davidpechon@...
