ESP8266 Community Forum

Hi, I'm sending AT commands from my Arduino to my ESP8266 and all is well until I try an AT+CIPSEND=267 to send 267 bytes of data and I get an error = "busy p... no tail ERROR".

What is the 'No Tail' trying to tell me ?

Thanks Mart

I can answer my own question - I have been missing the terminating carriage return ( '\r' ) from the command.

All I want to say is: drop the AT command idea

The default AT firmware sucks and is only nice to have a first play with the ESP, not to actually use it.
If you do want to use the AT command set, you'll probably have more chance on the Espressif BBS (the maker of the chip and the AT firmware), since people over here tend to prefer custom firmware instead of the default.

Thanks for your feedback. You're right,. I am a newbie and am using the AT command set as I already had an Arduino, and I have used AT command many years ago... An integrated boar5d would be the way to go....,

I've solved this issue as I was missing the '\r' character from the end of the command - I think that is what the 'no tail' message was telling me.
