Exactly, but I don't use STA mode only. I use AP or AP+STA. In mode AP+STA and when STA is unassociated the transmission (frames) comes at random intervals. Perhaps a module esp8266 is searching STA SSID and the CPU i overload ?

P.S Sorry for my English

- Sun May 24, 2015 1:29 am #18289 Your English is fine.

I get you entirely. Can you open an issue on the github repository (https://github.com/beckdac/ESP8266-transparent-bridge): https://github.com/beckdac/ESP8266-tran ... dge/issues

That way we can track it more easily. I haven't reproduced this problem, but it sounds like you have worked it well enough to test. Thanks!

First of all I'd like to apologize because I just received my first ESP-01 modules and have not done enough homework.
I want to use it as a serial cable alternative and this firmware seems to be very close to the thing I need.
I tried to flash the binary files 0x00000.bin and 0x40000.bin to appropriate addresses using nodemcu firmware programmer,
but after programming I get:
Fatal exception (29): epc1=0x40240652, epc2=0x00000000, epc3=0x00000000, excvaddr=0x00000404, depc=0x0
0000000
This happens with all the 4 pcs of ESP-01 that i received.
What could be the cause?
With best regards,
Marek

I'm not having any luck with getting this to work... Could someone please check and see what I'm doing wrong?

What I've so far tried:

1. I flash "v0.9.2.2 AT Firmware.bin" or "AI-v0.9.5.0 AT Firmware.bin"
2. I configure the esp8266 to connect to my router as a client, then confirm that I have an IP address:
   
   AT+CWMODE=1
   AT+CWJAP="ssid","password"
   AT+CIFSR
   
   Reboot, still good.
   
3. I use "flash_download_tool_v1.2_150512.exe" to flash 0x00000.bin and 0x40000.bin to their respective address, un-check the rest. Except for the address, I use the default settings. I'm just using the pre-compiled binaries from github.

After that, the esp8266 no longer connects to my router. On the serial side, I just see garbage characters at either 9600 or 115200 when I power-on the esp8266.
