Running a HC-05 Bluetooth and the Zio Zio Qwiic OLED Display (1.5inch, 128x128) not working

Since I cannot run the inbuilt BLE - not sure when, I use a standard HC-05 which I can run without anyproblem.

Then I want to display messages using the Zio OLED. The display is not working. But if I run the OLED example, it works.

Any assistance will be appreciated.

// put your setup code here, to run once:

}

void loop() {

// put your main code here, to run repeatedly:

if (BT.available())

{

Serial.print((char)BT.read());

OLED(); // NOT WORKING BUT IT DID DELAYED.

}

if (Serial.available())

{

BT.print((char)Serial.read());

}

}

// OLED BT

u8g2.setFont(u8g2_font_unifont_t_chinese2); // use chinese2 for all the glyphs of “你好世界”

//u8g2.setFont(u8g2_font_b10_t_japanese1); // all the glyphs of “こんにちは世界” are already included in japanese1: Lerning Level 1-6

u8g2.setFontDirection(0);

u8g2.firstPage();

do {

u8g2.setCursor(0, 15);

u8g2.print(“Bluetooth Hello World!”);

u8g2.setCursor(0, 40);

u8g2.print(“你好世界”); // Chinese “Hello World”

//u8g2.print(“こんにちは世界”); // Japanese “Hello World”

} while ( u8g2.nextPage() );

delay(1000);

}

Edit - found my own answer - I did not setup to use the u8g2.begin () and also u8g2.enableUTF8Print();
