If the ESP8266 doesn't keep Tx low long enough then it won't reset the attached nano. And since the nano has an on-board USB-TTL chip with an auto-reset circuit, the hardware mods would be a bit different than for the pro mini.Ralph Doncasterhttps://www.blogger.com/profile/00037504544742962130noreply@blogger.comtag:blogger.com,1999:blog-6245413346375218188.post-84939338458417068592015-02-08T14:14:48.133-08:002015-02-08T14:14:48.133-08:00I can't make this work.

I'm trying to reset an Arduino Nano receiving serial at 115 200 baud from an ESP8266 that runs firmware that makes it a transparent bridge. <br />Is the bitrate important for this solution to work?Egil Opsahlhttps://www.blogger.com/profile/13760430990159536922noreply@blogger.comtag:blogger.com,1999:blog-6245413346375218188.post-48931234864496387852015-02-08T14:12:14.183-08:002015-02-08T14:12:14.183-08:00This comment has been removed by the author.Egil Opsahlhttps://www.blogger.com/profile/13760430990159536922noreply@blogger.comtag:blogger.com,1999:blog-6245413346375218188.post-42148834485202283542014-05-07T07:21:17.917-07:002014-05-07T07:21:17.917-07:00Jan, you're right about the PL2303HX clones. ...Jan, you're right about the PL2303HX clones.

USB serial adapters based on that nifty FT230X would probably be cheaper and definitely smaller like that one on tindie.com (https://www.tindie.com/products/jimparis/microftx-usb-serial-breakout-1/) This might come in handy for my eeZeeProp Propeller breakout too.
