I recently purchased the Parani SD100 bluetooth to serial adapter to permit wireless debugging abd downloading to our robot. It is able to transmit data from the RC back to the pc just fine on COM9 so I am able to see all my printf output. However I cannot get it to download new code to the RC. The dialog at the bottom of the download screen reports the correct com port (COM9) it shows Com Port is Open a couple of times and then show the "Please press PROG button error message. I have fixed the baud rate at 115200 and set Hardware Flow control. Is there something else I nee to set to allow me to download my code via this wonderful device?
You can try turning off the Write Verify. This can also create new problems. If this does not work, then there is a timing issue in the protocol which we can not support.
