Hi, I am a use a ESP-12 in AP mode, I am trying to send ascii characters from the console of monitor serie, when the number of these is less than 127 characters I can be received correctly to the other side, but when the number of characters is higher I can not receive anything...
Someone can tell me what is my error?
Is there any restriction on the number of transmitted characters?
Here is my code:
