Intro: Testing a Viper Bluetooth Smart Start Module
For some time now I had a Viper Smart Start Bluetooth module. I got this despite lackluster reviews on amazon. I powered it up and yes it worked via Bluetooth. This is part of my cell phone universal remote program (the others being successfully implemented are controlling of all air conditioners, TV, my gate, front door, multimedia playback on my HTPC/Home Automation PC).
Sadly my viper alarm is outdated and even with the optional harnesses I could not make the module talk to my Viper alarm. Sigh.
Three months later into the present, I took the module out of preservation mode (i.e. a plastic bag). This time my aim is to make it work with my Viper alarm via some good ole fashion hard wiring!
This instructable is the first step prior to wiring the new arrangement into my car!
Step 1: The Module and the Relays.
The manual pdf for the module I attached for your viewing pleasure. The module has outputs for:
Each activated output goes to 0V i.e. they are all active low. When the command from my Android phone goes to the module, the relevant output wire goes to 0V. Really easy huh?
Now, for anyone with an old Viper alarm, ANY alarm or NO ALARM, using a couple relays will allow you to use this Smart Start Bluetooth module on ANY vehicle.
I used a spare 12 volt, 6 relay card. I have this card set to active low to turn ON the relays. Very cool product again from Amazon. Each relay channel has a test push button. I also set the relays to momentary mode (other modes include latched and alternate).
Step 2: Using the Free Viper APP.
Press and hold the pairing button on the module until the LED goes red then blue. Release that button.
When you first pull up the app, select Cars. Click add a module and it will turn on your Bluetooth for you (if needed) and then pair with the module. If this process is not done in 60 seconds then the module times out. Just repeat the pairing again.
Pairing is done only once. Once connected, the Home tab in the app will show the Bluetooth icon nice and proud. Now commands can be sent to the module and confirmations received from the module. How cool is that?!
I however love to test for worst case scenarios. What if I walk out of range, or restart my phone or temporarily disconnect the car battery? The error message on lack of communication will pop up. The easiest way to fix this is to restart the phone and it will connect again provided I'm in range (approximately 100ft line of sight).
I'm happy with this little module and soon I will transplant it into my car. Stay tuned!
