pi-star 4.1.6 command pistar-bmapi fails

Post by DF9FZ »

If you try to execute f.ex.

Code: Select all

pistar-bmapi dropdyn 2
an error (see below) occurs.
One reason could be, that due to editing the configuration files with some editor a stray '\r' is at the end of the line (perhaps editor uses DOS and not UNIX mode).
what happens is, that after the DMRID is extracted from a configuration file a carriage return is left at the end of the shell variable 'DMRID'.
With that variable a URL will be constructed which gets a '%0D' (URL encoded \r) added to the DMR-ID which will not be welcomed by the Brandmeister server and generates an error.

Easy to fix in /usr/local/sbin/pistar-bmapi:
Insert after the 'fi' around line 40 a new line with

Code: Select all

If you want to check, whether you have such an error case, surround this line with echo outputs:

Code: Select all

echo -n $DMRID|hd
#echo -n $DMRID|hd
and execute the command:

Code: Select all

pistar-bmapi dmrid
If both output lines do not differ and contain digits only, you're not having this problem with stray \r's.

The error output of pistar-bmapi looks like that:

Thank you, I have added that to the code revision for today (updating to add support for BM APIv2)
