ESP8266 Community Forum

- Mon Apr 29, 2019 2:26 pm #82071 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

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.

Assumption is the mother of all f*ckups. At least: that's what I'm assuming.

- Fri May 03, 2019 10:50 am #82135 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.
