getting the module to work smoothly is a bit of a challenge with the device talking duplex . have noticed that the response part that is required to verify action seems to always be preceded by two cr's (ascii 13) as circled in the attachments .
the latest firmware revision makes things a bit better by slowing to 9600 baud and giving the pic a bit more time to work
its all good fun
thanks to henrik for a good starting point
