Mark,

Had a little time this evening and compiled the latest firmware.
It compiles just fine now on Debian 8 (Jessie).

Quick output from my setup - serial output and not Tx'ing for real just yet (although the  board LED indicates it is Tx'ing in the right places).
It hears a lot from my current igate and digipeater wink

Mark,

I get the same errors when compiling MicroAPRS and MicroDigi, however, I get no errors when compiling MicroModem

I have also tweaked my files to make the images in MicroDigi and named MicroDigi.hex etc

I grabbed the new repo and compiled again (I also get pretty much the same errors as Stanley - I compiled on Debian Wheezy).

I see incoming packets being repeated (by monitoring a 2nd rig and watching the Tx LED on MicroDigi - I'm not yet transmitting on MicroDigi).
I now do not see anything on the serial line.

On a side note Mark, I see in device.h
#define OPEN_SQUELCH false

Is it OK to set to
#define OPEN_SQUELCH true
as I run open squelch.

I found this interesting circuit for running open squelch and the TNC (pretty much any TNC) set for closed squelch
http://www.ok0bez.com/files/aprs/TNC2_G … uelch_DCD/
I have most all the components, so may glue one together and see how it performs.

I'll try to do some more testing soon...

Nigel.

Hi Mark,

I saw the files during the middle of the evening, downloaded the repo, built a hex file and loaded it to my Pro Mini (running @ 5v but with a 3v3 ADC).
I think I grabbed it before your last change/upload later in the night, so will make a new hex file.

It was receiving and decoding live data and appeared to be re-transmitting as the Tx LED was lighting up (I didn't have it physically cabled to the Tx).
Monitoring the serial port, it reported WIDE-1 and WIDE-2 with the appropriate packets (but nothing else outputted to the serial line).

I'll report back when I get some time to make some proper tests (busy weekend coming up !!).

Nigel.

Hi Mark,

Great stuff, I will post my comments on the new firmware thread.

Nigel.

#6 Re: General discussion » Modern Hardware and Software for Digipeater... » 2015-05-15 08:00:14

OK, I think we have met over on RCG in the past (although I don't post on there much these days).

Nigel.

@ GaryMortimer

Are you from the UK and into FPV?

Nigel.

#8 Re: General discussion » Modern Hardware and Software for Digipeater... » 2015-05-14 13:26:29

Great news Mark - really apreciate your effort.
Let us know when the firmware is ready for download & testing as I am happy to be a Beta tester and give feedback to you.

Kind Regards,

Nigel.

Hi Mark.

Any news on progress for the digipeater firmware?

Nigel.

#11 Re: General discussion » Modern Hardware and Software for Digipeater... » 2015-04-30 09:22:55

Good news Mark.  I am also more than happy to be a beta tester.

An idea for the FTDI power saving is to have a header on the PCB with a jumper to apply power or not as needed.

Another use of such a low power digipeater is for Amateur Radio emergency groups (RAYNET in the UK) as I have been talking to some guys around here and they currently use R-Pi + Baofeng + small lead acid battery.
It works, but is quite heavy and lasts for a day or so.

I am testing a Baofeng UV3R which will run quite happily on 5V (remove the battery as it's only 3.7V).  The PA chips are the same as in the UV5R and the UV5R uses a 7.4V battery.  All other internal voltage regulators are 5v tolerant.
I supply the 5V from a radio control uBEC, like this
http://www.hobbyking.com/hobbyking/stor … ipoly.html
The output from these is quite 'clean' and they are quite efficient (no heat like you get with linear regulators).

Keep up the good work Mark!

Nigel.

Hi Mark,

It would be fantastic if you were to create a single board digipeater - I'm sure there would be some real interest in it (and push sales along a bit?!).
Even better if it could also query a weather station over serial as well and transmit the data periodically.
I know a friend is looking for exactly this at a model radio control flying club that is 'out in the sticks' with no mains power, but they do have some solar power available.  They are looking to regularly get local WX conditions only without the need to drive to site and find it is too windy or raining for example (digipeating is not on their priority list).

I am interested in putting up a WX + digipeater at our local radio club, also no mains power, but due to have some solar (and maybe wind generated) power at our hilltop club site.
We are lucky to have a diesel generator for weekly club night/weekend contests etc, so battery top-ups should be fairly regular.

Looking forward to this in eager anticipation...

Kind regards,

Nigel.

Thanks for the input.
My biggest obstacle is I'm more the hardware type than software - I can understand some basic stuff, but actually writing/programming is beyond my aged comprehension I'm afraid !

Can microaprs be made to work as a single board digipeater?  Are there any working examples of that?
As a fixed station, there's no need of GPS data and simply a single entry for lat/long would suffice.

Thanks in advance.

I have been lurking here for a while as I see this as perhaps the most modern development of low power, stand alone Hardware and Software (firmware) for APRS.

I am trying to find something that fits my current need, that is for a solar powered, APRS digipeater and Weather Station data transmitter.
Most of what I find on the internet is often out-dated, power hungry or proprietary (not open source).

I already have a Raspberry Pi running DireWolf + Baofeng HT, which works really well, but is still a little power hungry for my needs (the R-Pi that is) !

So, can microaprs/micromodem be turned into a standalone, digipeater and ideally with the ability to query an attached weather station and transmit it's data at regular intervals (similar to a GPS input)?
I can't find anything that fits my needs and hope micromodem/microaprs would be able to fit my needs.
I'm sure there is a need for small, low power/low cost 'fill in' digipeaters as coverage in my area is sparse at best as the countryside is quite hilly.


Regards,

Nigel.
