Bluetooth Connection for NexGen Wifi Module


The LED on the module is flashing green which indicates that the module is running normally, however when I tried to connect my device to the module via Bluetooth, it said “NexGen cannot connect”. What can I try to solve this?



Did you enable Bluetooth on the module? By default Bluetooth is not enabled.

Also keep in mind this is a Bluetooth 2.0 device not Bluetooth 4.0 which may make it incompatible with your device.

Yes I got it connected to IOrelay app thanks!
Also is there a way to make it so two specific relays are not on at the same time? For example, if I were to have 8 relays, I would not want relay 7 and 8 to be on at the same time. So turning on relay 8 would turn off relay 7 and vice versa.


If you are using the IORelay app you can do this using Macros. Use the set bank status commands outlined in this documentation:

Is there a way to have this feature while powering the relays from the tab that lists all the relays? I just don’t want to have to go over to the macros section and run the macro every time for the feature to work. If not is there an alternative way to implement the feature I mentioned?

Honestly the IORelay app has been discontinued. We are no longer maintaining it due to low user volume. I can however tell you that you can configure the app to open the Macros page when the board is selected from the device list. This way you do not have to switch to the Macros page. Is that what you are looking for?

Essentially, I am trying to toggle the relays on and off using macros so I can implement the feature I mentioned but I also want to be able to visually show that the macro has been run. Something similar to the power button in the page that lists all the relays.

Also thank you for the information provided before, much appreciated.

Hi Rich,

Yes, being able to view the status of the relays from the Macros page would be nice. I agree. We however never implemented that in the app. If you would like you can modify the app yourself or hire a developer to do it for you. The source code for the Android app can be found here:

Source code for the iPhone app can be found here:

Thank you Rich,
