- Fri Oct 23, 2015 9:24 am #32121 Thanks ! It's good to hear I am not being a complete moron with this.... I will try what you all have suggested and see what comes of it.... will update with my success.

Update...........

1st .... BarnabyBear - Thank You for the post and pretty pic.... my problem was indeed lack of the correct connections.... the pic you put together was a HUGE help.

2nd... I did hookup to a separate 3.3v supply... going to try converting back to see if I was just lacking connections.. or if power also had something to do with it....

Now for another big mystery.... I most likely would not have lost a day if I had the correct connections....

It turns out, that the text I posted in the original text, seems to be from booting.... and still requires 76800 baud to see it.... BUT... once booting occurs, I MUST change my serial baud to 115200 in order to boot into what ever 'boot loader' is brought up.... guessing it is the jump command from the boot.... I get the following after boot and after the changing to 115200 baud....

Code: Select allAi-Thinker Technology Co. Ltd.

ready


and then, if I send an AT+GMR to it, I get the following.....

Code: Select allAT+GMR

AT version:0.25.0.0(Jun  5 2015 16:27:16)
SDK version:1.1.1
Ai-Thinker Technology Co. Ltd.
Jun 23 2015 23:23:50

OK


So, I seem to be in good shape now.... If anyone knows what I am booting into please let me know.... is it LUA of some sorts ? Or just a loader AI-Thinker put on there ?

Thanks again everyone !

TJ

Hi, please note that after reading the post I directed you too in the clear light of day. I found that the order of events for flashing was not ideal and have since added this amendment.

EDIT: Sorry the 'To flash line' contains a sequence error and should read.
1. To flash you need to power down or press and hold the reset button.
2. Press and hold the GPIO 0 button or short to GND.
3. Power up or release the reset button.
4. Release the GPIO 0 button or remove the short.
5. Start flash within about a minute.

REASON FOR EDIT: If an ESP has firmware loaded that controls GPIO 0. In the event that GPIO 0 is set high at the time that you press the GPIO 0 button or short to GND, to enter flash mode. It is likley that the output could be damaged.
Hence the edit to remove power or reset before grounding the output. This would not affect factory units only when custom firmware is loaded.
