Exception 29 while sending values from HTTP GET to esp12f
Posted: Sun Jul 10, 2016 12:23 pmI am working on HTTP GET Request. I have created ESP wifi as web server. It creates a access point with IP address : 192.168.4.1 When my android app is connected to web server, it sends values every 50ms on 192.168.4.1/R"VALUE". Value is integer type (0~1023). Example :- 192.168.4.1/R546
However, it is working fine when I send values every 1s, but esp crashes, when IP is hit every 5ms second. I have captured the crash detail on serial monitor. Attaching the file and code as well. Kindly help.

WiFi.mode(WIFI_AP); //Our ESP8266-12E is an AccessPoint
WiFi.softAP("LED_Downlight1", "12345678"); // Provide the (SSID, password); .
server.begin(); // Start the HTTP Server
IPAddress HTTPS_ServerIP = WiFi.softAPIP(); // Obtain the IP of the Server
Serial.print("Server IP is: "); // Print the IP to the monitor window
Serial.println(HTTPS_ServerIP);

String request = client.readStringUntil('\r');

request.toCharArray(myTestUrl, 100);
char *Red = strstr(myTestUrl, "/R");
