How to determin which BT adapter to use? #20
Description
Hello,
I used successful our great work on Raspbian. Thank you for that.
Now I chaged to dietpi and node v19 and "rocket-nuimo": "^1.2.1",
With the built in BT adapter of Pi4 anything works fine.
This is my code working with the internal BT adapter of Pi4
'use strict';
const { DeviceDiscoveryManager} = require('rocket-nuimo');
// Device connection manager
const manager = DeviceDiscoveryManager.defaultManager;
start();
async function start() {
const session = manager.startDiscoverySession()
console.log('Waiting for device...')
var device = await session.waitForFirstDevice()
console.log('----- Appeared deviceId: ' + device.id);
if (await device.connect()) {
console.log('Connected to Nuimo Control');
}
else {
console.log('No connection');
}
}
After my script ran I can see in bluetoothctl:
[Nuimo]# list
Controller E4:5F:01:85:E7:2A rooExtend [default]
Now I added the USB BT antenna and did a reboot. The antenna works as I see.
# hciconfig
hci1: Type: Primary Bus: UART
BD Address: E4:5F:01:85:E7:2A ACL MTU: 1021:8 SCO MTU: 64:1
DOWN
RX bytes:7363 acl:95 sco:0 events:379 errors:0
TX bytes:8595 acl:88 sco:0 commands:290 errors:0
hci0: Type: Primary Bus: USB
BD Address: 00:E0:4C:7B:7B:03 ACL MTU: 1021:6 SCO MTU: 255:12
UP RUNNING
RX bytes:7438 acl:0 sco:0 events:510 errors:0
TX bytes:22021 acl:0 sco:0 commands:440 errors:0
The external antenna is hci0. With bluetoothctl I set it to be the default adapter
[bluetooth]# select 00:E0:4C:7B:7B:03
Controller 00:E0:4C:7B:7B:03 rooExtend #1 [default]
[bluetooth]# list
Controller E4:5F:01:85:E7:2A rooExtend
Controller 00:E0:4C:7B:7B:03 rooExtend #1 [default]
To be sure I only have the hci0 up and running I blocked hci1 with rfkill:
# rfkill
ID TYPE DEVICE SOFT HARD
0 bluetooth hci0 unblocked unblocked
1 wlan phy0 blocked unblocked
2 bluetooth hci1 blocked unblocked
Now if I start the scripts I see
----- Appeared deviceId: c810cec31489
But no connection will be made.
Funny enough: Same antenna, same dietpi running on a Nanopi Neo R2S Box (that has no internal BT controller) works like charm.
Help would be appreciated.
Thanks DrCWO
