Hi tlRmfj. Thanks for the feedback and sorry to hear you're having trouble. A couple questions for you to help figure out what's going on here:
What ICS distribution are you using on your Nexus S? Did you get it directly from your carrier, from Google, or is it a third-party build?
Can you verify that both the Dijit application and the Beacon firmware are up to date? The most recent Dijit version is 0.9.59 (on the Android Market. You can install the Griffin Utility from the Market to update your Beacon firmware if needed.
I've used the product pretty extensively with both a Nexus S running 2.3.x and another handset running ICS and have not seen this issue. If you're using a third-party distribution of ICS, it's possible that the bluetooth drivers there are causing this issue.
