I spoke to an OTS guy.

The OTS service requires L2CAP connection oriented channels. Some phones, but not all supports this. Basically, the OTS service is not standard BLE, which is why the RX / TX scheme is used a lot.

Hello,

I see that there is an OTS example in SDK15.

SDK\examples\ble_peripheral\experimental\ble_app_ots

SDK\examples\ble_central\experipmental\ble_app_ots_c

The example is also described here.

I haven't studied how the OTS service works in detail (you can find it here). However, I see that the OTS service in the SDK does not follow the spec yet (see here).

I believe you would need an app to use OTS on a phone, although I haven't tried it. As mentioned, our OTS implementation is not following the spec yet. I wasn't able to connect to it with anything else than the central OTS example.

However, I would agree that it is unnecessary that everyone has to reinvent the wheel. I will talk to someone who has worked with the OTS example, and check what the plan for this is.

Best regards,

Edvin
