First I would like to explain that I have had 5 (yes 5) sync modules fail over the almost 12 months that I have had the Blink system - some of them wouldn’t work at all, some of them worked then failed during operation and then two of them would not reconnect no matter what I did after I had to (very reluctantly) disconnect them - praying that they would connect again and of course they didn’t want to reconnect.
The frustration anyone is having with this will not equal the stress I went through and only a few days ago I went shopping for a complete new competitor solution - but none matched what my Blink system was capable of for my purposes.
So first of all I need to thank Kevin at Blink for his break through ideas which I will progress towards shortly.
Please NOTE I have no technical expertise so some of these steps may be ‘argued’ whether or not they are needed but this is what I did and it worked on ALL 5 FAILED sync modules.
First of all it is obvious that you should check you have all your other ‘stuff’ (computer, laptop, etc) working well with your modem/router and ensure that you have no issues. If you have a dual channel modem/router with 5Ghz and 2.4ghz Kevin at Blink suggested that I turn the 5Ghz off - which I did. This immediately helped the app to find the correct 2.4ghz network.
Also, ensure that your Serial numbers on ALL components have the 3rd digit matching (this is the region identifier). Mine is a Zero on everything and this is the USA region number that works in Australia. UPDATE: I have been assured by others at Blink that although the 3rd digit of the serial number DOES indicate the region, the matching of the 3rd digit is not as important as the region matching. That is, a different 3rd digits should work provided it is for the same region. All my 3rd digits match so I can’t personally confirm this. USA has a few different numbers so it may be something other than a zero.
The next suggestion was to place the Samsung Android mobile phone next to the Sync module and turn on mobile data (unlike most other people I do not access data on my mobile phone so this was new to me). Then I create a hotspot to tether to myiPad mini 4. I used the Blink app on my iPad to do the set up. Note: when using the iPad Blink app when told to ‘Retry’ you will notice the option to try to connect manually highlighted - try that option it can work.
I did this for 3 of the Sync modules and they immediately connected and did a Sync module update. I then went to the Cloud icons on the bottom of the app and tapped them. Next select change wifi and follow the prompts but this time select the normal home modem wifi channel. The Sync modules should try to connect BE PATIENT leave the Sync modules connected even after it tells you to retry - a couple of the modules connected AFTER I was told to retry.
For two of the sync modules this did not solve the problem. I have an Android mobile phone and an Apple iPad mini 4 with a SIM card in it. So I changed the hotspot to my Apple iPad and used the Android phone Blink app instead and again waited after being told to ‘Retry’ THEY CONNECTED!
One last tip - if these steps don’t work. Unplug the module, find the ‘factory reset’ tiny switch next to the USB plug (use a paper clip or something small) hold in the switch - you can feel it click - whilst still holing it in reconnect it with the power and keep holding until the red light flashes. The module is now reset and try again.
I cannot answer any technical questions but after lots of stress they all now work. The mobile hotspot idea seems to allow connection to be re-established in a way my modem didn’t allow - who knows why? Hope someone out there has the same result.
