[env:nodemcuv2] platform = espressif8266 board = nodemcuv2 framework = arduino monitor_speed = 115200 lib_deps = knolleary/PubSubClient@^2.8 Problem Description
In my code I have WiFiClient espClient and WiFiClientSecure updateClient, and they have irrelevant usage.
When updateClient is used by ESPhttpUpdate.update, espClient is disconnected in ESPhttpUpdate.onProgress, as you can test in the sketch:
MCVE Sketch
#include "Arduino.h" #include <ESP8266WiFi.h> #include <ESP8266httpUpdate.h> #include <PubSubClient.h> #define ssid "ssid" // Change this #define password "password" // Change this String upUrl = "https://bin.bemfa.com/b/3BcN2Q1NGY4NWFmNDI5NzZlZTNjMjY5M2U2OTJhNmJiNTk=light002.bin"; char serverName[] = "baidu.com"; WiFiClient espClient; void onStart() { Serial.println("onStart"); Serial.printf("WiFiClient is %sconnected.\r\n", espClient.connected() ? "" : "NOT "); } void onEnd() { Serial.println("onEnd"); } void onProgress(int cur, int total) { Serial.printf("onProgress at %d of %d bytes.\r\n", cur, total); Serial.printf("WiFiClient is %sconnected.\r\n", espClient.connected() ? "" : "NOT "); } void onError(int err) { Serial.printf("onError, err code = %d.\r\n", err); } void updateBin() { WiFiClientSecure updateClient; updateClient.setInsecure(); ESPhttpUpdate.onStart(onStart); ESPhttpUpdate.onEnd(onEnd); ESPhttpUpdate.onProgress(onProgress); ESPhttpUpdate.onError(onError); t_httpUpdate_return ret = ESPhttpUpdate.update(updateClient, upUrl); switch (ret) { case HTTP_UPDATE_FAILED: Serial.println("HTTP_UPDATE_FAILED"); break; case HTTP_UPDATE_NO_UPDATES: Serial.println("HTTP_UPDATE_NO_UPDATES"); break; case HTTP_UPDATE_OK: Serial.println("HTTP_UPDATE_OK"); break; } } void setup() { Serial.begin(115200); WiFi.begin(ssid, password); while (WiFi.status() != WL_CONNECTED) { delay(500); Serial.print("."); } Serial.println(""); if (espClient.connect(serverName, 443)) { if (espClient.connected()) { Serial.println("Connected to https://baidu.com."); } updateBin(); } } void loop() { } Log
........... Connected to https://baidu.com. onStart WiFiClient is connected. onProgress at 0 of 305120 bytes. WiFiClient is NOT connected. onProgress at 0 of 305120 bytes. WiFiClient is NOT connected. onProgress at 4096 of 305120 bytes. WiFiClient is NOT connected. ... Did I miss anything or this is normal?
How do I keep espClient CONNECTED during ESPhttpUpdate.update? Thank you.
