Great!
I'm not sure... Have you tried connecting pin 34 (the one that was 3.3v) to a GPIO pin on Espruino? It may be that the act of connecting it to 0v (when you want to send/receive data normally) is enough to reset it such that when you raise it to 3.3v again it listens for AT commands again?
Worst case you could connect pin 11 (which is reset) up to Espruino. Pulsing it to 0 (1=normal, 0=reset) would reset it and you could enter AT mode again that way.
