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.

SoftwareSerial BT(0, 1);

void setup() {
// put your setup code here, to run once:
BT.begin(9600);
Serial.begin(9600);

}
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());
}
}
void OLED()
{
// 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();
