Hi there,

I’m trying to reconnect using the AUTOCONN=2, but it doesn’t work for me.

I tried it with a mobile phone (HFP) and a BLE device. I paired them both, so they are in the Paired Device List (PDL).  
But when I manually set the remote address, then WRITE and RESET the bc127, it does not autoconnect to the defined address. Nothing happens on console except the start-up code (…READY). But the configurations stayed permanent, the AUTOCONN and the REMOTE\_ADDR is set.  
If I use AUTOCONN=1 it’s working, but I want to have control which device shall reconnect, e.g. not the phone but the BLE device.

Maybe the following is related to the problem: When I read the REMOTE\_ADDR parameter, it not only showing the BT address. The HFP device’s address is followed by 002A, the BLE by 005A:  
REMOTE\_ADDR=123456789ABC002A  
or  
REMOTE\_ADDR=123456789ABC005A

Is this just a internal mechanism to save the profiles of the paired device?

How can I establish a reconnect / auto-connect after reset with AUTOCONN=2?

I’m using Melody V7.2.

Regards,  
Alex

@alho,

The autoconn only affects BTC connections and not BLE

I have the same problem as alho.  
When I set the REMOTE\_ADDR=30243284BD21  
the remote address is stored like this: 302432BD210084

Here is the Log:  
Sierra Wireless Copyright 2018\<\r\>  
Melody Audio V7.2\<\r\>  
Build: 1534785311\<\r\>  
Ready\<\r\>  
SET REMOTE\_ADDR=30243284BD21\<\r\>  
OK\<\r\>  
REMOTE\_ADDR=302432BD210084\<\r\>  
OK\<\r\>

Can anybody help?

Edit: With Melody 7.3 the problem is solved. But the reconnect with AUTOCONN=2 is still not working.  
Any Ideas?
