Problem changing baud rate using ESP8266 as modem when using AT commands

[ZamperSPA]

[ x ] Bug or issue with library functionality (ie, sending data over TCP/IP)

What are you working with?

Modem: ESP8266 , ESP-01S
Main processor board: Atmega1284P
TinyGSM version: 0.11.5 , but the new version also has the bug

Code:

void setBaudImpl(uint32_t baud) {
    sendAT(GF("+UART_CUR="), baud, ",8,1,0,0");//<---add the comma before the 8 to fix
    if (waitResponse() != 1) {
      sendAT(GF("+UART="), baud,",8,1,0,0");  // Really old firmwares might need this //<---add the comma before the 8 to fix
      // if (waitResponse() != 1) {
      //   sendAT(GF("+IPR="), baud);  // First release firmwares might need
      //   this
      waitResponse();
      // }
    }
  }

Scenario, steps to reproduce

use setBaud() function

Expected result

change the baudrate of communication

Actual result

ERROR is displayed on the serial monitor

Debug and AT command log

I did not save the logs, I simply added the comma and the issue was fixed.
