BT Connection to slave device fail

[dedesite]

Hello, I'm opening a separated bug for this problem already mentioned in this issue #98.

I'm trying to pair my Inkplate 6 with a BT 3.0 Keyboard and it doesn't work, even with the "ESP32 Wroover Module" board from this definition : https://dl.espressif.com/dl/package_esp32_index.json

Here is the code I use, you may want to change the address or the name to get it working :

#include "Inkplate.h"
#include "Arduino.h"
#include "Fonts/Open_Sans_SemiBold_32.h"
#include "BluetoothSerial.h"

const GFXfont *text2_font = &Open_Sans_SemiBold_32;

BluetoothSerial SerialBT; //Object for Bluetooth

String MACadd = "DC:2C:26:E4:67:D6";
uint8_t address[6]  = {0xDC, 0x2C, 0x26, 0xE4, 0x67, 0xD6};
String name = "Bluetooth USB keyboard";

Inkplate display(INKPLATE_1BIT);

int incoming;
bool connected;

void setup()
{
    display.begin();        // Init library (you should call this function ONLY ONCE)
    display.clearDisplay(); // Clear any data that may have been in (software) frame buffer.
    //(NOTE! This does not clean image on screen, it only clears it in the frame buffer inside ESP32).
    display.display(); // Clear everything that has previously been on a screen
    display.setCursor(150, 320);
    display.setTextSize(1);
    display.setFont(text2_font);

    // Tentative BT
    Serial.begin(9600); //Start Serial monitor in 9600 also tried with other rates
    SerialBT.begin("ESP32_KEYBOARD", true); //Name of your Bluetooth Signal
    display.print("Bluetooth Device is Ready to Pair");
    display.display();
    // connect(address) is fast (upto 10 secs max), connect(name) is slow (upto 30 secs max) as it needs
    // to resolve name to address first, but it allows to connect to different devices with the same name.
    // Set CoreDebugLevel to Info to view devices bluetooth address and device names
    //connected = SerialBT.connect(address);
    connected = SerialBT.connect(name);

    if(connected) {
      display.println("Connected Succesfully!");
      display.partialUpdate(false, true);
    } else {
      while(!SerialBT.connected(10000)) {
        display.print("Failed to connect.");
        display.partialUpdate(false, true);
      }
    }
}

void loop()
{
 
}

Is there any progress on your side to get BT working in both slave and master mode with your board definition ? Thanks, Andréas

Any update on this issue ? I really want to be able to use Inkplate 6 as a e-typewriter and BT seems to be the only "easy" solution for this. PS/2 and USB keyboard may work but need extra hardware and tweak for the software to use GPIO extension.

We tried to recreate the example with newer board definitions, but unfortunately, it didn't work properly. If there is progress, we will make an example in the Inkplate library.

Thank you for the update, I hope this will work someday.
