Also, do I enter my access-point's ssid and password in the esp.ConnectAP?
ex...
esp.ConnectAP("accesspointname", "password", false);

Currently getting failed to acquire IP via uart over serial.

Initialized Uart...
Initialized ESP, connecting to AP...Failed to acquire IP!

Thanks for making this for the TivaC tm4c!

When trying larger amounts of data through (+18kB/s) a socket (_espClient::SendTCP()), sending routine often times out waiting for ESP reply. This is caused by the unexpected reply from the ESP, or wrong logic in the processing function triggered by the ISR.

This bug limits the speed to 4-5kB/s instead.

Steps to reproduce:

1. Open a socket to TCP server (ESP8266::OpenTCPSock)
2. Periodically (200Hz) send small chunk of data (100B) using ESP8266::GetClientBySockID()->SendTCP()
3. Observe the amount of data received on the server side
4. Observe TX, Rx lines from the ESP with logic analyzer

Expected behavior:
Login analyzer:

• Timing to send the data fits with the baud rate being used
• Time between consecutive sends fits with the sending frequency
  TCP server:
• data arrives at a rate of 19.5kB/s +/-5%

Actual behavior:
Login analyzer:

• Timing to send the data fits with the baud rate being used
• Time between consecutive sends is the sending frequency, plus few milliseconds that it takes for watchdog to time out
  TCP server:
• data arrives at a rate of 4-5kB/s +/-5%
