I have a ESP-01s and have connected it to my PC with a serial to USB adapter. I am now using Putty and At commands and here is what I get:
I have connected to my wifi using AT+CWJAP=
Then I set AT+CIPMUX=0
I then am able to connect to thingspeak using: AT+CIPSTART="TCP","api.thingspeak.com",80 (I have also tested AT+CIPSTART="TCP","184.106.153.149",80)
Now here is where I run into trouble: AT+CIPSEND=51

I then enter
GET /update?api_key=U500NH0PAMAF927A&field1=255
I then get
busy s...

Recv 51 bytes

SEND OK
This does not update my thingspeak so I have tried to resolve the busy s... by increasing the byte length but whenever I use any number besides 51 it returns No tail Error
I have tried doing ctrl M and then ctrl J and have tested using every variation of code aswell as looking at data sheets and do not know what to do.

I also used AT+CIPMODE=1 & AT+CWMODE=1 before even configuring my wifi

FYI, MATLAB answers is the preferred location for ThingSpeak Community support.

I usually find it easier to connect the ESP directly to the wifi instead of using AT commands. You can program the ESP with an Arduino UNO or FTDI cable.

I also recommend looking at the ThingSpeak library. There is an AT command example in there.
