POSTING failing after around 10 minutes + SENDFAIL error
Posted: Tue May 02, 2017 1:38 pmMy project has an Arduino Zero board (Atmel Cortex ARM M0+ Plus) as the main MCU that comunicates succesfully to a ESP-12 module, using the Standard hardware UART (115200bps).
This the firmware that my ESP8266 module is using:
I am using the bportaluri/WIFIEsp library to communicate with the ESP module using stardar AT Commands. I am posting information to an influxDB server, and it is working, although I can see the SEND FAIL message coming back to the main MCU, and also after some time the main MCU freezes.
This is the relevant part of my code:
In Setup:
In Loop:
Finally the POST Function:
Everything is clear and itorks for 10 minutes, however this is the result in the Serial Monitor when I enable thedebug option:
Any help?, what is happening?, do you recommend me some other Arduino library to communicate using the standard AT commandS?

Ai-Thinker Technology Co. Ltd.I am using the bportaluri/WIFIEsp library to communicate with the ESP module using stardar AT Commands. I am posting information to an influxDB server, and it is working, although I can see the SEND FAIL message coming back to the main MCU, and also after some time the main MCU freezes.
This is the relevant part of my code:
In Setup:
Code: Select all
#include "WiFiEsp.h" // ESP8266 WiFi Library
#include "WiFiEspUdp.h" // ESP8266 Wifi UDP Library (NTP Server)
WiFiEspClient WiFiClient; // Wifi Client
WiFiEspServer WiFiServer(80); // Wifi Server
WiFiEspUDP Udp; // UDP instance -> send / receive packets over UDP
Serial1.begin(115200); // UART (Serial1, pins 0,1) -> ESP8266
delay(50);
WiFi.init(&UART); // Wifi Module Serial Init
while ( WiFistatus != WL_CONNECTED) { // AP Connection: attempt to connect to WiFi network
// Connect to WPA/WPA2 network
WiFistatus = WiFi.begin(ssid, wifiPass);
}In Loop:
Code: Select all
// (1) Incoming messages from ESP8266
while (UART.available()) { // PUART <- ESP8266
char c = UART.read();
SerialUSB.print(c);
}
// (2) POST to INFLUXDB SERVER
// measurement[,tag_key1=tag_value1...] field_key=field_value[,field_key2=field_value2] [timestamp]
if ( (millis() - WIFITime) >= COM_WIFI_INTERVAL ) {
WIFITime = millis();
// Building POST Body (Payload): InfluxDB:Measurement + tags
char payload[128] = "";
sprintf(payload, "%s,HwID=%s,CustID=%s,Zone=%s,Loc=%s V=%03d.%01d,IA=%03d.%01d,PFA=%01d.%02d,WA=%05d,VAR=%05d,VA=%05d", \
DataMeasurement, TagHwID, TagCustomerID, TagZone, TagLoc, \
(int)Meter.getVRMS(), abs((int)(Meter.getVRMS()*10)%10), \
(int)Meter.getIRMSA(), abs((int)(Meter.getIRMSA()*10)%10), \
(int)Meter.getPowerFactorA(), abs((int)(Meter.getPowerFactorA()*10)%10), \
(int)Meter.getActiveA(), (int)(Meter.getReactiveA()), (int)(Meter.getApparentA()) );
// Server POST Function
POSTData(payload);
}Finally the POST Function:
Code: Select all
void POSTData(char* Body) {
// (1) Establish TCP connection with Server
if ( WiFiClient.connect("www.XXXXXXXX.tech", 8086) ) {
// Make a HTTP request: Headers + Body
WiFiClient.print("POST /write?db="); // -> Headers
WiFiClient.print(influxDB);
WiFiClient.println(" HTTP/1.1");
WiFiClient.print("Host: ");
WiFiClient.println(server);
WiFiClient.println("Accept: */*");
WiFiClient.println("User-Agent: Arduino/1.1");
WiFiClient.println("Connection: close");
WiFiClient.println("Content-Type: text/plain");
WiFiClient.print("Content-Length: ");
WiFiClient.println(strlen(Body)-1);
WiFiClient.println();
WiFiClient.println(Body); // -> Body
delay(50);
//WiFiClient.stop();
} else {
WiFiClient.stop();
}
}Everything is clear and itorks for 10 minutes, however this is the result in the Serial Monitor when I enable thedebug option:
