It still shows strange characters when I uses "esp8266.begin(115200);":áµ#Ð"Ri#øá¥Õ|5"Á¿VØRiÖ*ká¥Õ|)0\Åó}Îñó%ÿxWù^}ùLÔ"ª¥ÅIs there any other possible baud rate? Or is there any way to check if my esp8266 is defective? Thanks for your help
Ups, wait, I got those messages only after I add "Serial.print(command);" inside "sendData" function. Otherwise I only got these strange characters:éKýÿòÔÿIÉJéúùùúÿýéÔÿ
I just noticed that mine has 2 LEDs too. But besides the red one, the blue one only blinks 2-3 times whenever I reset my arduino then it stays off. These are the only messages shown in my serial monitor:AT+RSTéJþÿAT+CWMODE=1IÉÔÿÿAT+CWJAP="ssid","password"IÉRòûôùúýÿéÔÿ
Thanks. I just tried it but couldn't make it work. The esp8266 couldn't connect to wifi (debugged through serial monitor). Its led is constantly red. Is because I only use arduino uno USB as power?
So we actually need 3 x 10 kohm resistors (instead of 2 x 1 kohm + 1 x 10 kohm), right? It would be helpful for newbie if you maintain consistency between the component list & diagram
