Because it's from DFrobot Tx-Tx and Rx-Rx. Their silkscreen was done this way. www.dfrobot.com/product-147.html. Normally for other FTDI Rx-Tx and Tx-Rx. Wiring is correct.
@@webslinger2011 hahaha incredible. They made a change to simplicity. But experienced people like us may fall into this lol. Normally uart protocol is clear rx to tx and vice versa, I think they made this change for new starters
@@webslinger2011 i was using a sparkfun FTDI so it shouldn't matter where was it bought from it's an FTDI module and were all made with the same purpose so unless there's something special about this particular unit i see no reason why it shouldn't have work, however i did managed to get it to work following my programming instincts.
@@webslinger2011 but to answer your question i when with the tx/tx || rx/rx using 5 wires config and although i did not get any visual confirmation from the serial terminal while executing at commands i did took notice of the hc05 module l.e.d confirming my commands and so i accomplish what i set out to accomplish.
@@arletpaz8010 As far as I know, I only need to connect 4 wires using DFrobot. Since I don't use sparkfun, I haven't used that extra wire connection you mentioned. Is it to reset after uploading/sending commands?
@@webslinger2011 no you misunderstood me the wire config is not special to that sparkfun product i've seen other tutorials using 4 wires setups, other individuals dont even use code and only use a blank canvas or blank sketch and actually upload a blank sketch as a way to clear the memory on the mcu but again nothing special, you can do any combination of the said above with FTDI or even with other arduinos the hc-05 does not care it just wants the said at commands thats all where it get it from is irrelevant, however the hc05 does require a specific activation setup and this is what you and i similarly do when we try to program it via serial com
Does not work!
Tx to Rx and vice versa.... Correct that info.

DID NOT WORK
What FTDI are you using? DFrobot website says connect tx-tx and rx-rx. Others connect tx-rx and rx-tx. Did you try switching pins?
