SimpleBLE.h example problem #373

Hi, I am running SimpleBLEDevice.h code on a NodeMCU ESP-32S board.

When trying to do ble.begin("ESP32"); on the setup the code gets stuck. Digging a little bit the code gets stuck inside ble_send_cmd() at the end

while(_vhci_host_command_running);
int res = _vhci_host_command_result;

It never gets out from the while.
Thanks

I'll give it a go hopefully sunday or monday and will reply back. It should work.

I did a good couple of hours digging through this. And there is no apparent reason why it would not work, but it does not. Callbacks are not called and the code can not progress. The included example in IDF has not changed either, so there are no clues to what has changed or what can be done. Maybe good time to remove that SimpleBLE example and be done for now.
My test GATT service is working, so not all is broken.

Where can I download and try your test GATT service?

Just for reference, I tested SimpleBLE around May 6th on ESP32-Bit/ESP32-T, and it worked at the time.

Which SDK did you use? I have ESP32_Core_Board_V2 and SDK:
ESP32 SDK: v2.0-rc1-761-g65acd99c
BTDM CONTROLLER VERSION: 010101
SimpleBLE not work :(
crash
while(_vhci_host_command_running);

I also had this problem with today's code. I did a
git checkout git rev-list -1 --before="May 05 2017" master
in esp32 repository and now when I run the SimpleBleDevice example I actually see the "Press the button to change the device name" prompt. I'm using the latest Arduino IDE.

I see multiple changes to BT related files in esp32 on May 6.

hope this helps.

That's what I used:
ESP32 SDK: v2.0-rc1-443-g3cad00f-dirty
BTDM CONTROLLER VERSION: 010101

The OP started to have the problem on May 11th, so something changed between May 6th and May 11th.

With the new code I have this

Press the button to change the device name

But pressing the button nothing changes. I can see on my phone ESP32 SimpleBLE but not pairing

Running the SimpleBLE example from Arduino IDE gives me this result and it's changing it's name:
