Hi, I have had problems recently with my SMS module, although it works every so often the status light will start to blink indicating a hardware problem (according to the manual). I have tried to upgrade the firmware to 1.03 but the upgrade always fails. I select the correct HEX file, click full operation DEBP, all starts correctly as per the firmware update instructions until I receive an error as dispalyed in the dialogue box...
2/7 retry = 256 Wait Asynchronous Dial-UP
ERROR!!
No.001 Download error
After clicking OK it requests I do download operation again, of which I do only to receive the same error. I have also tried going to version 2 but the same problem as above occurs...
Any ideas?
Regards
