If iPhone can connect to the Bluetooth PCB, that means, at least, PCBA is good. The most possible reason is the Bluetooth version.
Bluetooth version is not compatible. Bluetooth is a communication protocol. If the Bluetooth headset supports a version of the Bluetooth protocol that is not compatible with other devices, the connection will fail.
- Try to consult Bluetooth chip suppliers and you can get a clear list of compatible phone.
- If you are a retailer, it would be better to classify this product by various Bluetooth versions before recommending products with proper Bluetooth to your customer. It is a good way to ensure consumer satisfaction in terms of product and sales service.
