    A bit of an update:

     

    I tried both a direction connection to the SIO and Stefan Both's Rverter circuit. Same commands, etc,

     

    One difference I noticed was that although AtariGeezer's test gave initial good results, the response seemed to garble after the first AT command. I can't say it's AtariGeezer's circuit, it could very well be my wiring.

     

    Here's the resulting pic of both:

    Yep, looks like you made a typo?

    AT+CIPSTART="TCP","broadway1.lorexddns.net",23. works

    AT+CIPSTART="TCP","broadway1.lorexddns.org",23 .won't <- you substituted ".net" for ".org"

    Somehow it was set at 70000 baud (?why?)

     

    I wrote a small BASIC, letting me send a string+CR+LF over the SIO.

    In my own monitor, I got wifi,ap,cipstart all setup.

    Module says OK to all.

    If that basic file configures the SIO port for different baud rates, could you post it :)

    Thanks,

    Jay

    Interesting that no one appears to be having much luck getting this to work. I was under the impression that someone had a while back and posted some videos that proved it. Was I imagining this?

     

    Starting to look like this isnt ready for prime time yet :).

    I'm trying to get my backup ESP-01 to work again after trying to flash zimodem to it. It's stuck at a strange baud rate like Mr. Ataris'...

    AtariGeezer with a different Rverter circuit than Both's claims he is able to connect.

     

    The one kicking nearly everyone's butt is the original ESP-01 with the original firmware.

    Seeing is believing :)

    One thing I noticed is that there is a high pitched audio squeal that goes up in frequency until it stops at the baud rate you have set the ESP-01 module to. I've noticed this with a direct SIO to ESP-01 and using both Both's and AtariGeezer's Rverter circuit. It happens on both ICET and BobTerm.

     

    Anyone else notice this?

    Yep, I hear it most at 4800 baud.

    Now I am trying to get something going.

    First I have issued ATE0, to kill echo, allowing me to use ESP8266 and Disk-SIO.

    Bobterm does not sendout "_" so I can not send the AT commands I want with bobterm.

     

    In my own monitor, I got wifi,ap,cipstart all setup.

    Module says OK to all.

     

    Now I do not know what to do next.

    PLATO loads, but does not continue (and I am connected to irata.online:8005)

    Bobterm does nothing too either

     

    When I have my ESP8266 setup and connected, how do I get on a BBS with Bobterm?

     

    Thanks in advance!

    Bobterm sends the underscore for me.

     

    Are you using the original firmware or have you flashed one of the modem emulators like ZiModem or other?

    Now regarding the Zimodem firmware. The way I did it was just send a pre-compiled version to the esp-01. It turned out that the version has problems saving changes (like wifi pasword or address book).
    This is a known bug of some esp-01s:
    So I ended up installing arduino and compiling Zimodem by myself. I also took advantage of having the code and set the default baud rate to 2400 and changed the Pet-ascii translation tables to Atascii-Ascii. All the menus and options still refers to pet-ascii translation (like atdp), I did not change that.
    It was pretty straight forward to write the firmware to esp-01 if you don't need to compile. In Linux I used esptool.py. Not sure how it will work on windows or macosx, probably it will work. Find all about esptool.py in the website:
    You need to do something like this to write the firmware (first you need to put the esp-01 in programming mode)
    sudo esptool.py --baud 115200 --port /dev/ttyUSB0 --before no_reset --after no_reset write_flash --flash_mode qio 0x00000 zimodem.ino.generic.bin
    I hope this help you guys in your endevoir
    ps: not sure if this forum accept .bin, hopefully it will work.

     

    Could you post the source with your changes?

    Finished my programmer / break-out board last night :)

    This is the response from my ESP-01:

     

    Ai-Thinker Technology Co. Ltd.

    ready

    AT+GMR
    AT version:1.2.0.0(Jul 1 2016 20:04:45)
    SDK version:1.5.4.1(39cb9a32)
    Ai-Thinker Technology Co. Ltd.

    OK

    I'll change the baud rate to 9600 and try on bobterm in a bit...

    Tried direct connection of ESP-01 module to SIO cable. No difference. Still just an echo of what I type in.

    This is perplexing, let's try something different.

    Connect the ESP Adapter back up to your Arduino and program the baud rate to 19200, then reconnect back up to the A8 and run Bobterm at 19.2 to see if that does anything.

     

    Another idea is to check the RX and TX voltages on the ESP Adapter when connected to the Arduino vs the A8.

     

    Are you just using the 1088XEL or have you tried another A8 too???

    Maybe you can draw the nand gates "inside box" to make circuit idea.more evident and less prone to errors

    The error in the previous post (pic now deleted) was how I wired up RX and TX the first time which was the mistake.

    I can visualize how the NAND Gates appear "in the box", it's really rather easy to do...

    But I will make an easy to read schematic on how to follow the easy diagram :)

    That looks pretty close to what I was doing. I'll try one final time to use the stock firmware to see if I can fix the problem. Thank you.

     

     

    Nice, My ESP programmer comes in Friday or Sat, as well as replacement ESP01 module. So I'll have a go at flashing the new firmware then. Thank you.

     

     

     

    I've got a 1030 in the closet that is gathering dust. If I can get this going, would be a excellent reason to bring it out of storage. Thank you again. ;)

    First thing to do is send the "AT+GMR" to see what version yours is and the "AT Firmware". Sending the wrong AT commands after that could brick you new ESP-01 too...

    I'm just trying to figure out why mine isn't working still.

     

    I've found a USB connector breakout board I bought some time ago and I'll be attempting to provide external power to the adapter if I can find a +5V USB power/charger cable that matches. :( Too many rotted USB power cables with incompatible connectors on the end......

    Did you try replacing the 74xx00 chip yet?

    This thing has a very minimal current draw from the SIO port...
