Ja mam chyba inną wersję, u mnie to wygląda tak, że łączy się tylko na komendy AT, transmisja działa, nie umiem z niej wrócić inaczej niż odłączając zasilanie, po rozłączeniu zasilania nic automatycznie się nie łączy z powrotem:
Oczywiście wpadłem na to, że pinem EN można wyłaczyć działanie modułu, co go właściwie resetuje, bo stan jest jak po odłączeniu zasilania, nie łączy się, ale w ten sposób już dałoby się dość prosto zasterować go z uC, wyszukać ten czy inny slave, połączyć, pogadać, zresetować stan pinem IO uC i nawiązać inne połączenie.
