ESP32 BLE library

Hi !

Is there anyone who succeed to connect ESP32 using Blynk BLE?
I tried to run the example, I successfully connected only once!
Now, when I try to connect, I have an issue.

Android 6.1
Blynk last beta 14.05.20
Blynk library 0.6.1

18:59:49.545 -> Waiting for connections...
18:59:49.545 -> [33] 
18:59:49.545 ->     ___  __          __
18:59:49.545 ->    / _ )/ /_ _____  / /__
18:59:49.545 ->   / _  / / // / _ \/  '_/
18:59:49.545 ->  /____/_/\_, /_//_/_/\_\
18:59:49.545 ->         /___/ v0.6.1 on ESP32
18:59:49.545 -> 
19:00:06.528 -> [17002] BLE connect
19:00:07.588 -> [18079] BLE disconnect
19:00:07.588 -> [18079] Disconnected

Unfortunately, I got the same issue

But, I thought I could connect ESP32 without local blynk server, but I was wrong !
We need blynk server connected to connect UI to BLE !
It is not very useful, compare to Virtuino that we can direct connect to BLE.
So I am using a simple android serial BT monitor, but it’s ugly :rofl:

That’s right. Must always have Blynk Server.
BLE <–> APP <–> Blynk Server
