SIM32 request password

[cherryphilip74]

Hi @Berg0162,
after a few years I’m back because I’m building a new Simcline V2 and I’d like to use the latest firmware with Virtual Shifting.
My hardware setup uses the XIAO ESP32‑S3 with OLED.
For now I’m testing only the Laptop ↔ Trainer pairing (with shifters).
I flashed the Smart‑MITM‑xtra library and I can see both the laptop and trainer MAC addresses in the Serial Monitor.
However, when I open Rouvy and try to connect to “SIM32” in the sensor list, I get a popup asking for a Bluetooth password (screenshots below).
I tested both:

• ENABLE_ZVS
• TRAINER_WITH_LEGACY_ZVS_SERVICE
  and in both cases I get the password request.
  Sometimes Zwift also shows a password popup.
  If I enable FTMS, instead of the password popup I get a Direto‑XR pairing window.
  Screenshots:

Could you help me understand what I’m doing wrong in the configuration or procedure?

Thanks for your feedback and time

Best Regards
Filippo

Quite missed you!
What laptop OS are you using, Windows 11 or macOS?
Has the Direto XR any BLE security activated in its settings?
Nobody ever reported this behavior ... I guess the laptop is bonding with the SIM32 and/or Direto, OR you have set encrypted BLE connections or something similar, otherwise passkeys are not requested for connection. You can check for bonded BLE devices with the registered BLE-devices in the Laptop OS.
When the SIM32 asks for a BLE passkey you can enter: 123456 and a shorter variant will probably work for the Direto!
Success, Jörgen.

I’m running macOS, and BLE security does not appear to be explicitly enabled. The system prompt is triggered only when the client application attempts to initiate a BLE connection with the trainer. The laptop is already maintaining an active BLE session with my own application. I will check BLE authorization from macOS. Of course I tried with: 000000, 012345, 123456 and so on

Would you like to keep us informed of your progress?
