If you have a device that reports MO-2BLE1-V2.01, you can typically confirm via:
Firmware version 2.01 may not include the latest security patches. Common risks: mo-2ble1-v2.01
Recommendation: If the device supports secure OTA, upgrade to a version that enforces LE Secure Connections. If you have a device that reports MO-2BLE1-V2
MO-2BLE1-V2.01
Low-power Bluetooth 5.2 module with integrated antenna Recommendation: If the device supports secure OTA, upgrade
| Problem | Possible Solution with V2.01 | |---------|-------------------------------| | Frequent disconnections | Check for BLE 5.0 compatibility; V2.01 may default to 1 Mbps PHY. Force LE 1M instead of 2M. | | High power draw | Look for debugging UART left enabled; disable in config. | | OTA fails | Ensure MTU size is ≤ 247 bytes (BLE 5.0 default). Older phones may need 185. | | Cannot advertise | Verify advertising interval isn't below 20 ms (violates BLE spec). |
The mo-2ble1-v2.01 relies heavily on its firmware layer. Unlike generic development boards, this module is often delivered with a pre-flashed real-time operating system (RTOS) – typically FreeRTOS or a proprietary microkernel.
