le-connection-abort-by-local on Raspberry Pi 4

[k2sebeom]

I am running on Raspberry Pi 4 Model B to connect with BLE devices.

When I run adapter.Connect, it always returns error "le-connection-abort-by-local."

BlueZ version = 5.66

package main

import (
	"fmt"
	"strings"
	"time"

	"tinygo.org/x/bluetooth"
)

func main() {
	adapter := bluetooth.DefaultAdapter

	if err := adapter.Enable(); err != nil {
		panic(err)
	}

	scanCh := make(chan bluetooth.ScanResult, 1)

	err := adapter.Scan(func(adapter *bluetooth.Adapter, device bluetooth.ScanResult) {
		println("found device:", device.Address.String(), device.RSSI, device.LocalName())
		if strings.Contains(device.LocalName(), "PD") {
			scanCh <- device
			adapter.StopScan()
		}
	})

	device := <- scanCh
	close(scanCh)
	adapter.SetConnectHandler(func(device bluetooth.Address, connected bool) {
		fmt.Printf("Connected to %s with %v\n", device.String(), connected)
	})

	time.Sleep(time.Second * 1)

	_, err = adapter.Connect(device.Address, bluetooth.ConnectionParams{
		ConnectionTimeout: bluetooth.NewDuration(time.Second * 100),
	})

	if err != nil {
		fmt.Printf("Failed to Connect %s\n", err.Error())
	} else {
		fmt.Printf("Connected to %s\n", device.Address)
	}
}

Have you tried connecting manually through bluetoothctl? Does it work there?
