Many users of Dasaita Android head units encounter frustrating issues when trying to establish a stable Bluetooth connection with their OBD2 devices. While theoretically straightforward, the process often becomes complicated, leading to connection drops or complete failure to pair. This article aims to consolidate existing knowledge and explore potential solutions for these persistent Dasaita Obd2 Bluetooth connectivity problems.
The core challenge seems to stem from the way Dasaita head units, particularly those running MTCD/MTCE firmware, manage Bluetooth connections for external applications. Unlike standard smartphones where Bluetooth pairing for OBD2 devices is usually seamless, Dasaita units may restrict access or prioritize certain Bluetooth functions over generic OBD2 data transfer. Users report being able to pair OBD2 devices with their phones without issue, confirming the OBD2 device itself is functional. However, when attempting to connect via the Dasaita head unit for applications like Torque or RealDash, problems arise.
Reported issues include:
- Inability to Pair: The OBD2 device is discoverable in the Bluetooth settings, but pairing attempts fail repeatedly.
- Freezing Applications: Apps like RealDash may freeze or become unresponsive when attempting to enable Bluetooth or connect to the OBD2 adapter.
- Limited App Access: External apps may not be granted the necessary permissions to utilize the Bluetooth module for OBD2 communication.
One user’s experience highlights a common scenario:
“I know it can be done, cause i once had a working setup on my device. Problem is i can’t get it to work again anymore after some firmware flashes and MCU updates. I did a lot of research, read a huge amount of posts and tried several solutions which did work for other people. Maybe some people find it stubborn, some say i can’t be done period, but the fact that i had it working once is eating me up.”
This frustration is echoed across numerous online forums, often buried within lengthy threads discussing firmware updates, MCU versions, and custom ROMs. Finding a clear, concise solution becomes a significant challenge for many Dasaita head unit owners.
To effectively troubleshoot and resolve these Dasaita OBD2 Bluetooth issues, we need to gather more information and shared experiences. Key details include:
- Dasaita Head Unit Model: Specific model name and Android version.
- MCU Version: (e.g., MTCE GS 2.72).
- Firmware Version/ROM: (e.g., Malasyk 6.2).
- Bluetooth Module: (e.g., SD-968).
- OBD2 Device Model: (e.g., Scantool OBDLink LX).
- OBD2 Device Firmware Version: (e.g., 4.3.0).
- Apps Used: (e.g., Torque, RealDash).
By compiling setups that have successfully established a Dasaita OBD2 Bluetooth connection, alongside those encountering issues, we can begin to identify patterns and potential solutions. Possible areas to investigate further include:
- MCU and Firmware Compatibility: Are specific MCU or firmware versions more prone to Bluetooth OBD2 issues?
