Dixprs handle .pkt & .myp packet

[Francis Lee]

Dear HA5DI

I would like to ask if an aprs message with ACK (end with {line counter ) sent by .pkt or .myp from external sources, does Dixprs will sent the message again if no ACK received ?

Hi Francis

the short answer is no. .pkt and .myp packets sent out only once independently their content.

At the moment you can't import a message to the DIXPRS message sending module. I add this feature to the todo list.

Dear HA5DI

Thanks your reply.

In fact I meet a problem on the spooling function. I feed some Wx data to Dixprs by .myp file. I write a python program and got the Wx data from local observatory, and feed the data to Dixprs spooling folder when news udpated. 

However, I found sometimes the .myp files was remove ( should be remove after sent), but there are no action shown in the status screen. The status screen should shown when Tx/Rx data.

I sent the data via all interface (*).

I check the Raspberry Pi resources by "top" command, the utilization is low, and seems not related to resources problem.

Any idea for this problem ?

Hi Francis,

it is race condition, DIXPRS is processing the import file before it is closed by its creator. It happenes randomly, depending on how often new file is added to spool directory.

I will fix it when I get some time.

Francis,

please find attached a new version of dixprs.py for DIXPRS 2.2.2 It checks the last modification time of import files and imports them only if it is more than 5 seconds old. Hopefully it will sove the problem. Just stop DIXPRS, replace the current dixprs.py with the new one and start it.

Let me know the result.

Regards... Bela, HA5DI

Hello  HA5DI

I tested the new dixprs.py for almost a month, here is the result.

1/ If my aprs message sent once only, some packet drop still happen.

2/ If my aprs message sent twice (with 1 second interval), all the first time packet was drop, but all the second time packet will be sent out. I identify the first & the second time packet by ack {01 and {02 .

Best Regards

Francis

Francis,

is the situation better than with the old file? Are you copying the file to spool from a different location or creating there?

Hello HA5DI

The .myp file created in the default spool folder /dixprs/spool/  by a python program.

If the aprs message packet sent once only, the result is similar to old one (sometime drop packet).

If sent twice (with 1 second interval), almost all 2nd time aprs message (with ACK: {02) ) sent (just drop 1 time according my result). But I do not know why all the first aprs message (with ACK :01) was dropped.
