Hi Stephen,
Thanks for the response. We are not considering connecting Arduino board to DF RObot 7000E. We are trying to access DF directly by bypassing to power up the DF & send and recive the data externally by using FT232L USB to TTL Converter.
We are able to receive the data from DF 7000E if we hold the boot button for couple of seconds but when we send its not responding. We were wondering if any one have similar issue in connecting directly to Df board and which ports they used in resolving the issue?
One post very close to the issue, posted by Mel
" Initially, I could not get the sample code to work, or the library, so I bypassed the arduino side altogether, and connected a UART directly to pins 7&8 and ground and talked to it directly. The unit seemed to have issues with baud, and some googling showed that the UNO software serial code got around this by trying to send the first command that would set the units baud from 115200 (too fast for sw serial) to 19200.Also worthy of noting - the UNO did not seem to have enough power to allow the unit to boot while holding the BOOT button for the documented 2 secs. Plugging the unit into an externally powered DUE solved this for me, but perhaps I have a faulty UNO regulator."
Any thoughts or ideas are greatly appreciated.
