BLE not compatible with my device

ERROR Code: Client busy or timeout

I'm trying to connect my Bluetooth BMS using an ESP32. In versions prior to Arduino ESP32 v2.x everything is fine, I can easily connect to BMS.

But when I change to NimBLE-Arduino which is more efficient and lightweight (That’s exactly what everyone was looking for), I can't connect to Bluetooth anymore. From v1.4.0 to v2.5.0 none of them work.

As far as I know Espressif move to Nimble in v3.0.0 (maybe not), so in Arduino ESP32 v3.x exactly the same as NimBLE-Arduino. I CANNOT get connected at all.

I try to refuse ConnParamsUpdateRequest just like "bool onConnParamsUpdateRequest(BLEClient *pClient, const ble_gap_upd_params *params) { return false; }", but nothing go better.

Below is the connection log:

this have been solved in https://github.com/espressif/arduino-esp32/issues/12222

...
  // if (rc != 0) {
  //   log_e("...", rc, BLEUtils::returnCodeToString(rc));
  //   m_lastErr = rc;
  //   return false;
  // }
...

So, anybody know whats going on?
