But if I try to get anything from the internet I get HTTP Response Code = -1. Stage 1: Installing the Proteus Setup file 4 Rite now this Arduino. So the question is: Has anyone seen this behavior and maybe give some hints about how I can get the internet connection to be consistent without needing a static IP? When I use a static IP then the static IP is assigned. If you installed the drivers for the CH340 on your computer but have issues connecting via serial terminal or uploading code using the Arduino IDE, there may be. I suppose other router wifi settings could also have impact. Changing that to 20MHz channel after a reset fixed it. When DHCP magically works it assigns: 192.168.1.159 Turned out that the router had wide wifi channel (40MHz) enabled by default. If I uncomment this line then it works fine If so then you can control it using your Arduino by wiring it back to TX-RX and RX-TX. Now open Serial Monitor and send AT command and see if it responds. Replace these with your WiFi network settingsĬonst char* ssid = "MYSSID" //replace this with your WiFi network nameĬonst char* password = "MYPASSWORD" //replace this with your WiFi network password Start by uploading blink sketch to your Arduino then connect it to your ESP8266 like this: TX-TX and RX-RX. It is almost as if the DHCP is failing to assign an IP and then returns some random default. Make sure the baud rate of the Serial monitor is set to the same. I have not seen this with any other device (like laptops or cellphones) NOTE: If no response is seen, try unplugging the UART to USB device and then plugging it again.If I factory reset my router then it works again for a few times.I've uploaded the FirebaseDemo code to my ESP but the ESP just print 'connecting.' on the serial monitor, which shows that it's not connected to the Wi-Fi. I'm just started using the ESP8266 Wi-Fi Module and the one that I'm using is ESP8266-01S. If I assign a static IP then it ALWAYS works and connects within seconds pauline95 September 25, 2019, 2:26am 1 Hi.Eventually it says "Connected" but the IP is completely wrong and it is not connected to the internet (GET request fails). When I connect it to the WiFi for the first couple of times I am not seeing any issues and the ESP8266 connects just fine.īut after an arbitrary amount of times (like when I restart the unit) it tries to connect for AGES (like multiple minutes). I am seeing some very strange behavior with my ESP8266. ![]()
