Kernel error / Uwatec Smart via irda
by Nick Hardy 09 Feb '15

09 Feb '15

I am trying to download dives from my Uwatec Smart Com on Ubuntu 14.10. I have tried to eliminate as much complexity and have downloaded the smart test app to gather info about the problem. In the below system log, I have captured the following actions: 1. insert the usb irda dongle. 2. run irattach irda0. 3. run a quick irdadump to make sure the system sees the dive computer. 4. run smart. The following lines are output: DATETIME 2015-02-09T01:21:20Z (1423444880) VERSION 0.5.0-devel (61e9847196b4e7f4e2c80e47dd6cd7070c9c4418) uwatec_smart_device_open INFO: Discover: address=16c40100, name=Aladin Smart Com, charset=00, hints=8000 INFO: Connect: address=16c40100, lsap=1 A few seconds later, a system error message pops up. The smart application never completes and can not be killed. The smart.log file is created, but nothing is ever written to it. I have cloned the current git tree and compiled the app successfully but it generates the same error. I'm happy to help debug if you'd like. Thanks!

[PATCH] Predator: don't report PPO2 unless in CC mode
by Dirk Hohndel 07 Feb '15

07 Feb '15

Sending this in OC mode is redundant and might confuse applications that assume they only get PPO2 data in CC mode.
