cDAQ-9191 drops wireless connection

[sfrosty]

I've been connected from my iPhone 5 to the cDAQ-9191 wirelessly for the last two days monitoring a sine wave using the cDAQ-9191 app on my iphone. The cDAQ-9191 is not connected to the hardwired Ethernet connection. I decided that I wanted to utilize the computer that I originally used MAX to configure the cDAQ-9191 for another purpose. Again, the cDAQ-9191 is communicating wirelessly with my iPhone displaying a sine wave that is being input to the 9215 module plugged into the cDAQ-9191. So I should think there is no communication between the cDAQ-9191 and my computer that was originally used to configure the cDAQ-9191 through the Ethernet hardwired connection even though it has an active wireless dongle plugged into it. However, when I accessed MAX and selected disable on the network tab, in that the cDAQ-9191 wireless was already configured a few days ago and was no longer needed, the wireless radio strength indicators on the cDAQ-9191 turned off and I lost communication to my iPhone! Evidently the cDAQ-919 is being accessed by my computer through its' wireless dongle and controlled by MAX?

It initially was quite an effort to get the cDAQ-9191 configured and successfully transmitting data to my iPhone. Many calls to NI. One thing I learned is that in order to reset the cDAQ-9191 you must hold the button in for at least 5 seconds or until the status light turns yellow. Another item of interest, a person should believe what he reads regardless of other input, the cDAQ-9191 currently only works in wireless mode communicating with an iPhone if being utilized with the NI 9215 analog input module. Another note: indications of changes or proper operations can take several minutes; if not more.

Is the cDAQ-9191 wireless mode still in the development and prove-out stages?

I'm thinking that recently changing my wireless dongle on my computer to ad-hoc mode probably allowed it to communicate with the cDAQ-9191 and send it the disable command wirelessly.

I know that I'm still in the development stages!

Hi sfrosty,

You may want to post this question here: https://decibel.ni.com/content/thread/12728?start=0&tstart=0 . That discussion is dedicated to support for the cDAQ-9191. You can probably get a more in-depth response there.
