Can't get past esp.ready() #8

Closed chall3ng3r closed 9 years ago

chall3ng3r commented 9 years ago

Hi,

I'm trying to get the example work, but it does not get past while(!esp.ready()); line.

MQTT and REST, both examples stop at this line, and on the debug port there's some random gibberish, something like B..aC^<kpWp~v| just after esp.ready() call. And I also see small blink of blue LED on ESP module.

I even updated the Arduino lib from pull request posted few hours ago on this repo. Still same result.

Any pointers where I should look for? wiring? baud rate setting?

try delay(1000) maybe reset command take a long time

Please update new commit, maybe the reason is CH_PD incorrect

I had the same issue -- in my case it was because I had forgotten that I'd burned the "AT" firmware to the ESP8266 board I was using. Re-flashing with the espduino firmware and fixing that CH_PD issue got me past that.

Other than that, seeing garbage on the debug port is, I think, most likely to be a baud rate mismatch.

Thanks guys for your reply. Gonna re-flash and update the espduino lib and try again.

I will post here my result soon. Thanks again.

i've changed proto buffer size of arduino from 1024 to 512 bytes, it's ensure everything better

chall3ng3r commented 9 years ago

I downloaded new update, re-flashed the espduino firmware and updated lib in arduino.

BTW, I am using Arduino Mega 2560 and have it wired like this: wp_20150314_002

Also, updated the code with correct Serial port representation. Using Serial as debug port, and Serial1 for ESP8266 module: screenshot_2

Now with everything updated, I see it would stop on esp.ready() call. Red and blue both LEDs are full on ESP module. There's one thing I noted, on Mega's 3.3v pin there's actually 3.6v.

Still trying to get it working.

Now getting this:

While researching, I found another firmware NodeMCU, which flashed and started up on first try. For now I gonna play with a bit more. Will try espduino again when I get the time. Thanks for your support, and keep up the good work you're doing on this project.

According to your wiring in the photo you are connecting the ESP directly to the MEGA? Be carefull ESP is 3.V Mega is 5v.
