So I gather a simple reset of the unit would not of worked? Or did you not want to go through the setup again?Ok I just spent two hours on it and indeed I finally managed to get through the wifi with the Laview_XXXXX passcode. I screwed up big time by activating the doorbell with batch configurator which means... I changed the admin password and cannot change it back to the activation code because the 6 letter code is too simple to be accepted by batch configurator or iVMS4200. It meant that the app could not get through the setup process because using my new password did not work with the RCA app. It uses the activation code for two steps and one of them must match the the hardcoded code. So... I simply decided to try changing the wifi settings from iVMS4200 so that the camera joins my wifi network. From there, the RCA app skept through the wifi settings requirement and asked me for my activation code. I used my new password once and then put in the activation code and I am now back in business. Now I know how to work it: the apps has restrictions as to what SID must look like for the doorbell. That's painful. The iVMS/ Batch configurator have restriction as to what the admin password must have, another painful thing. After inclusion, I finished the doorbell configuration on the Guarding Vision App... phhhew
What is weird is that even the Laview one app is expecting and HSDB2_XXXX SSID and Passcode, not just the RCA app. In the future, if this happens again, I will know that I don't need to do anything with the app.
