It is relatively easy in simple projects, where all parameters are included into source code. But I would like to have possibility to reconfigure working device, for example change SSID and password, to connect it to another Access Point.
How should I do it? Is registration my own AT commands proper way? What actually happens, when I execute at_init()? Is entire AT "engine" available then (with all standard commands) or only set declared by me?
And BTW, another question. What should I do, to make module keep trying to connect if, AP is not available during its initialization?
