The following code is used to crearte le conn with the bluetooth device but this is not working and connection is not created. This is used in @abandonware/noble package.
const { minInterval = 0x0006, maxInterval = 0x000c, latency = 0x0000, timeout = 0x00c8 } = parameters;
const cmd = Buffer.alloc(29);
// header
cmd.writeUInt8(HCI_COMMAND_PKT, 0);
cmd.writeUInt16LE(LE_CREATE_CONN_CMD, 1);
// length
cmd.writeUInt8(0x19, 3);
// data
cmd.writeUInt16LE(0x0060, 4); // interval
cmd.writeUInt16LE(0x0030, 6); // window
cmd.writeUInt8(0x00, 8); // initiator filter
cmd.writeUInt8(addressType === 'random' ? 0x01 : 0x00, 9); // peer address type
(Buffer.from(address.split(':').reverse().join(''), 'hex')).copy(cmd, 10); // peer address
cmd.writeUInt8(0x00, 16); // own address type
cmd.writeUInt16LE(minInterval, 17); // min interval
cmd.writeUInt16LE(maxInterval, 19); // max interval
cmd.writeUInt16LE(latency, 21); // latency
cmd.writeUInt16LE(timeout, 23); // supervision timeout
cmd.writeUInt16LE(0x0004, 25); // min ce length
cmd.writeUInt16LE(0x0006, 27); // max ce length
debug("create le conn - writing:", ${cmd.toString('hex')});
this._socket.write(cmd);
