Just did a job with an SX80. Wish I would have read this thread before quoting the programming!
v1.0 of the module is indeed a mess.
Known issues: directory dialing can only dial using "method 1". If there are two methods defined in the codec database, you can't use method 2 (e.g. SIP). Workaround - save a temporary local copy of the directory on the codec, with only 1 method defined for each entry.
Camera presets don't work (saving or recalling). Workaround - use an SIO outside of the module.
Although the module's programmer wasn't previously aware of this issue, mine wouldn't authenticate with the codec until I rewrote that section of the module. It was too chatty, which kept interrupting the authentication sequence.?I re-wrote that logic outside of the module, while suppressing the module TX until authentication was acknowledged. Presumably this will get added to the "known issues" list.
I'm told that a new version will be released in early Oct2014. Until then, I'm happy to share my workarounds - just contact me via the LiquidPixel Group website.
