Hello i need help
When i add Adafruit_SSD1306.h and run display
BC95Udp.h can't work
Thank you.
Mycode :
#include <Adafruit_SSD1306.h>
#include <Adafruit_GFX.h>
#include <Wire.h>
#include <Arduino.h>
#include <ArduinoJson.h>
#include <AltSoftSerial.h>
#include "BC95Udp.h"
#include "EmonLib.h"
#include <Dns.h>
#define OLED_RESET 4
Adafruit_SSD1306 display(OLED_RESET);
AltSoftSerial bc95serial;
BC95UDP udpclient;
uint8_t buff[64];
DNSClient dns;
IPAddress remoteip;
int x;
void setup() {
Wire.begin();
bc95serial.begin(9600);
BC95.begin(bc95serial);
BC95.reset();
Serial.begin(9600);
Serial.print(F("Starting"));
while (!BC95.attachNetwork()) {
Serial.print(".");
delay(1000);
}
dns.begin();
dns.getHostByName("ddns name", remoteip);
Serial.print(F("NB-IOT module IP address : "));
Serial.println(BC95.getIPAddress());
udpclient.begin(8053);
udpclient.beginPacket(remoteip, 55555);
display.begin(SSD1306_SWITCHCAPVCC, 0x3C); //initialize I2C addr 0x3c
display.clearDisplay(); // clears the screen and buffer
display.setTextSize(1);
display.setTextColor(WHITE);
display.println("Thailand");
display.display();
}
void loop() {

root.printTo(text);
Serial.println("\n\nSending UDP payload : ");
Serial.print(text);
udpclient.write(text,strlen(text));
udpclient.endPacket();
udpclient.parsePacket();
size_t len = udpclient.read(buff,64);
Serial.println(F("\n\nReceive UDP payload : "));
Serial.println(len);
printHEX(buff, len);
delay(2000);
}
String str_char(char val[]){
String str_a;
for(int i=0;i<strlen(val);i++){
str_a += val[i];
}
return str_a;
}
void printHEX(uint8_t *buff, size_t len) {
char myStr[len];
String aaa;
for (int i=0; i<len; i++) {
if (buff[i]<16) Serial.print(" 0");
else Serial.print(" | ");
Serial.print(buff[i]);
}
}
