F6BVP

Bob Bennett
 

I am setting up F6BVP's latest version on my Pi3. Unfortunately when I run the grep command to replace the F6XYZ with my own call I get the following:


pi@raspberrypi /etc/ax25 $ sudo grep -rl F6XYZ * | xargs sed -i 's/F6XYZ/NZ2Z/g'

sed: couldn't open temporary file ./sedDOm9au: Permission denied


Did I do something wrong?

Using the UDRC™ on a Raspberry Pi for 1200/9600 Packet

 

There is a new Wiki entry on using the UDRC™ on packet radio with the direwolf soundcard TNC

See: https://nw-digital-radio.groups.io/g/udrc/wiki/UDRC%E2%84%A2-and-Direwolf-Packet-Modem

Using the UDRC™ + Raspberry Pi 3 + 7″ Touchscreen Display + a FT-817 (or other radio) makes a great little desktop Xastir based APRS viewer.

Raspberry Pi 2 or 3 using Shoutcast to stream audio

Noel Petit
 

This is slightly off topic, but if there is a better group I would to hear about it. 


Has anyone had luck with the Raspberry Pi 2 or 3 as a Shoutcast streamer from a USB audio converter? All of the Shoutcast references I find are 3 or 4 years old. i have had no luck compiling and running Shoutcast 1.2 on Jessie.


Thanks,

I downloaded Jessie 2016-03-18 from Raspian. I just imaged another card and the hciattach.service file isn't there.  No update or upgrade.  I do see the hciuart.service file.

You have to add the last step. Add file: hciuart.service then open it up and add [unit] [service] and the other one just like his instructions.

Re: TNC-Pi with Raspberry Pi 3

John
 

You are the second person who has raised this issue.  I can think of two possible reasons that might have caused this.  The other person who ran into this issue had downloaded the OS from NOOBs rather than Raspbian.  I went in this morning and clarified the manual that I had used the straight Raspbian download.  

A second possibility is that when I did this I edited the file before doing the update/upgrade.  It is possible that the file was eliminated in the upgrade process.  Before I edited this file, it existed, but it was blank.

I'd appreciate any feedback that others might have about this.

Re: TNC-Pi with Raspberry Pi 3

 

Thanks to John Wiseman, Richard Bates and others, I have been able to update the TNC-Pi manual to provide detailed instructions on how to get the TNC-Pi working with the new Raspberry Pi 3. It is available now at:

www.tnc-x.com/TNCPi.pdf

Any update on the TNC-pi9600?

Re: TNC-Pi with Raspberry Pi 3

I had a tnc pi, the only thing I can say based on experience with other devices is this.

Any daughter boards on the pi3 need to have the serial login debug disabled, and Bluetooth to be disabled. Also the process is different for wheezy and Jessie.

Hope that helps

Re: Translating CAN data to APRS telemetry format

David Clark
 

Sounds like an I retesting project.

I'm curious about what a CAN sentence looks like. I have work with it before.

It might be possible to use the "experimental" data field to send the sentence as is and recover it and decide it on the other end.

On that note, what are you using for Rx of the data?

What is the data rate of the CAN data?

Thanks

I am assisting a local high school's solar car team with a telemetry system to monitor voltage, current and temperature of the vehicle's solar panel, battery and motor. This information is available onboard the vehicle and displayed on a commercial meter. I've been successful in reading the CAN data using a PICAN2 and a PI2. I've also successfully used a TNCPI with the Pi2. Not successful in getting the data from the CAN data stream to populate the required 3 APRS telemetry sentences. Any examples or suggestions?

Larry,
I don't know if anybody has suggested this test....
Put a couple of 1000mF capacitors in parallelwith the battery that is causing the problems, then perform your test again.
The capacitors should be rated for a voltage higher than the battery you are using, and make sure you connect the battery and capacitor polarities correctly.

     Anker was kind enough to send me a new battery but it was the same problem. The new battery was tried on a Raspberry Pi B,Pi 2B, Pi 3, and an Odroid C1+ All four would not shut down and or went into a reboot loop from the very start.

     Since this all started trying to replace an aging battery could someone recommend a battery that is known to work with these computers?

Re: Portable Battery Problem

David Cooley
 

Any battery that isn't "smart" should work fine.
it's very possible that the change in draw right as it shuts down has the smart function confused... then it see's drain again and the voltage probably interrupts for probably a fraction of a second, making the pi reset and reboot.
you really need to put a meter across the 5V at the pi and watch it while you shut it down may need an analog meter if it's a quick "blip" in the voltage.

Re: Translating CAN data to APRS telemetry format

 

You might find this useful for sending APRS telemetry with a Raspberry Pi.


https://github.com/wb2osz/direwolf/raw/master/doc/APRS-Telemetry-Toolkit.pdf


It describes scripts and methods to generate APRS telemetry. Includes a complete example of attaching an analog to digital converter to a Raspberry Pi and transmitting a measured voltage.
