Battery drains faster than expected
Functionality is good, but I only got about 18 hours of continuous use instead of the advertised 24. Might depend on transmission frequency settings.

Excellent for prototyping wearables
Integrated this module into our fitness tracker prototype. The BLE connection is stable and the HR data aligns well with our reference equipment. Great value for developers.

Accurate data for fitness app
We used this for a university project involving heart rate variability monitoring. The data export features are robust and easy to parse.

Good signal quality
The ECG signal is clear during static tests. Movement artifacts are present during high intensity, which is expected for this form factor. Documentation could be more detailed.
Q: What type of electrodes does this use?
A: This module utilizes dry metal contact electrodes designed for chest strap integration, requiring no gel or replacement pads.
Q: Is the SDK documentation available publicly?
A: Yes, our SDK documentation and sample code are available on our official GitHub repository linked in the user manual.
Q: Can I access raw ECG data via Bluetooth?
A: Yes, the BLE protocol supports streaming raw ECG waveform data as well as processed HR and HRV metrics.
Q: Is this module waterproof for swimming?
A: The module has an IP54 rating, making it resistant to sweat and splashes, but it is not suitable for submersion or swimming.
Q: What is the maximum Bluetooth range?
A: In open space without interference, the effective range is approximately 10 meters. Walls and obstacles may reduce this distance.
