Answers checklist.

I have read the documentation ESP-AT Programming Guide and the issue is not addressed there.

I have used the latest released firmware or have updated my ESP-AT branch (master or release) to the latest version and checked that the issue is present there.

I have searched the issue tracker for a similar issue and not found a similar issue.

General issue report

After first BLE connection failure with broken pipe it cannot connect to anything without a reboot.

So it's getting stuck.
AT+BLEINIT=1

# ensure not connected
AT+BLEDISCONN=0
ERROR

# connection fails 
AT+BLECONN=0,"73:f7:7c:18:70:b1",1,5
+BLESCANDONE
+BLECONN:0,-1
ERROR

# ensure not connected
AT+BLEDISCONN=0
ERROR

# connect to any other
AT+BLECONN=0,"5f:29:72:aa:82:c4",1,5
+BLESCANDONE
+BLECONN:0,-1
ERROR

# same error to any other addresses without reboot
It doesn't even seem to wait for timeout period, fails instantly.

Reboot solves the issue. AT+BLEINIT=0 seems to simply reboot the system, which is slow.
