I have first tried running your command without network connection and indeed got the same error as you: Hmmm...that could help me try a few ideas. Are you absolutely sure that you are using STA(tion) mode and you're connected to AP with internet connection? Yes. My original line of code read like ...

Thanks, but I cant see anything in that short file that sheds any light on this error code...

I get this problem with ANY host - which is why I think it is some weird generic DNS tyype error...

I have an ESP8266 board which is clearly connected to my AP and thence to the wider internet. For example it is using the socket interface to regularly upload sensor values to Thingspeak. But I can only do this if I hard-code the Thingspeak i/p address in my socket code. Attempts to use gethostbyadd...

It would be nice to have a non-hacky way of doing something like this. I guess I could try implementing that myself but this is really the first time I've even looked at a non-trivial C program, so someone else is probably more qualified. Is there any update to this? Are you now able reliably and r...

Thanks for that.

it does not crash at 200Hz. I would never want to go that slowly anyway - it takes ~ 5 seconds to get a reading from the sensor.

At least now I know a lower limit should I have to reduce clock frequency to cope with longer cable runs.

2) I'm guessing that this is due to the watchdog timer kicking in, but to confirm you would need to check the reset code that is printed right after the board resets. Thanks - when the board resets I get a load of gibberish ending with: 삌l��lrl�l��|��rrnb��l���b�b쌜�����bllbl��ln�l`��ln�prl�l��|��rr...

Hi, I am experimenting with some I2C sensors, and have been playing with the clock frequency to see how it affects reliability. Three specific questions: 1) The Micropython default clock speed (if you create an I2C object but do not give a 'freq=' parameter) - is it 400kHz? 2) I notice that if I red...

Hi mcauser thank you for the code appreciate :D . may i know where do i need put resistor?do i need to put resistor for SDA and SCL line?Sorry for my noob question do you have schematic where i can follow to put the pull out resistor? Yes, on both. The optimal value for the resistors depends on clo...

I note that there have been mentions on the forum about 'over the air' updates ("OTA"), and I was wondering what is the current state of play?

Do we have that functionality available with Micropython?

'Under the surgeon's knife' : http://internetofhomethings.com/homethings/?p=538 This article is from last year - maybe the longevity of the ESP flash has improved since then. I would be interested to know if others on this forum have hit a 'barrier' at the 20-30 re-flashes point where the device sta...
