| v1.1.1 ai-thinker-v1.1.1.bin the default baud rate is 115200 Important Note: The AT command must be end with "\r\n". For Arduino, must type the AT command like this Serial1.print("AT+GMR\r\n"); Not like this: Serial1.println("AT+GMR"); So the hardwareSerialMonitor sketch will not work now. v0.9.5.2 ai-thinker-0.9.5.2-9600.bin The default baud rate is 9600 ai-thinker-0.9.5.2.bin The default baud rate is 115200 AT+GMR AT version:0.21.0.0 SDK version:0.9.5 v0.9.5 beta ai-thinker-0.9.5.bin AT+GMR 00200.9.5(b1) compiled @ Dec 25 2014 21:40:28 AI-THINKER Dec4 |
