TCP reset (RST ACK) on the 2nd call in Simple WebServer #1956
Description
Simple web server resets connection on second node.js call (plain browser does the same if you hit refresh fast enough!).
ESP32 debug window only says "RES:0 ERR:128", irrespective if the client call was disconnected or not:
Wireshark shows:
Hardware:
Board: ESP32 Dev Module (ESP32_Core_Board_V2)
IDE name: Arduino IDE
Flash Frequency: 80Mhz
PSRAM enabled: no
Description:
I have a simple web server which works fine if I call it only once from node.js and then close the connection, but ESP32 resets the connection on a 2nd call if I try to keep it open:
Error: read ECONNRESET
at _errnoException (util.js:1019:11)
at TCP.onread (net.js:608:25)
This is happening with both sdk 1.0.0 and 1.0.0-rc4.
Sketch:
#include <WebServer.h>
...
server.on("/peek", [](){
String webString = String(getMicrons(getPacket()));
server.send(200, "text/plain", webString);
//delay(50);
});
...
void loop(void) {
server.handleClient();
