Dear beckdac,

your project is exactly what I was looking for :+1: Unfortunately, I do not have windows and therefore cannot compile your code :( After cloning I successfully uploaded the firmware, but cannot connect to the device. As far as I understand, the supplied binaries are for the dynamic configuration. In my case the ESP8266 does not open any AP, so I have no change of sending any AT commands via TCP.

Would it be possible to include a binary version in the repo that just opens an default AP, takes a default IP and port and start listening?

Cheers,

PA7T

PA7T: The binaries are there already: https://github.com/beckdac/ESP8266-transparent-bridge/tree/master/bin It works for me (on Windows 7). Remember you need to use telnet to use the +++AT commands.

PA7T commented 9 years ago

hmm I uploaded them successfully, but I cannot find an AP on the air in the end. so no chance to use telnet...

I'm having the exact same issue with the prebuilt bins. Uploaded with nodemcu flasher windows gui and with the python based esptool.py and i get the same results ether way.

Over here it works, although for some obscure reason I had to do the cycle twice on one esp8266 (flash normal firmware, configure ap, flash bridge firmware).

I found my problem. it appears i had a corrupted download of "eagle.app.v6.irom0text.bin" the md5 should be E812D4D75B9C8809805995991E9DEC13 mine was D391F00B4B4861AC9B0BFE191B48BA1D This time I downloaded the complete ziped project, then extracted the bins and flashed it and it worked. Remember a zip file gives you another level of error checking.

PA7T commented 9 years ago

in my case the MD5 is fine and I flash with: sudo esptool.py --port /dev/tty.usbserial-A6* write_flash 0x00000 eagle.app.v6.flash.bin 0x40000 eagle.app.v6.irom0text.bin power cycling does not help. I just do not see anything on the air :(

Did you try my workaround?

eriksl commented 9 years ago

BTW the version of jvdbroek I didn't get working, no reaction of the device whatsoever.

beckdac commented 9 years ago

I just went through this myself setting up new devices. I completely borked some of the modes. After doing this, I reflashed the stock AT firmware paying particular attention to the esp_init and blank.bins, e.g. on this page: https://github.com/espressif/esp8266_at/wiki/Compiler
