Hello,
I'm working on the security pairing of DA14583. My sensor is based on DA14583 as a peripheral and my phone works as a central device. Since the DA14583 is claimed by Dialog as BLE v4.2 also BLE v4.2 supports LE Secure Connections pairing method with ECDH cryptography. So, I would like to use this feature. I read the tutorial Training_05_ble_security_example_v1.1, but it mentions only the PassKey pairing method only. OOB is not possible since the peripheral cannot afford this. Could you please provide some hints how to implement this with SDK5.0.4?
Thank you!

Hi quangng,
The 580 as the 583 is 4.2 qualified, that means that only the mandatory features are supported, the secure connections is an optional feature for the 4.2, hence the 583 doens't support the LE Secure Connection feature. Please check the below post:

Hello,
Is it possible to configure DA15483 in dual mode? Or should I use a GAPM_RESET_CMD in order to perform a role switch? How can I assign a new role after issuing a GAPM_RESET_CMD?
Thank you beforehand,
Patrick

Hi Amrein,
Thanks for your question online. If you are starting a new design, we would strongly recommend to start with DA14531 or DA14585/586 products and our latest SDK6.0.14, as it is much more improved. We have a lot of code examples and improved documentation, and there is also software roadmap support. There is not any software roadmap support for DA14580 product family and SDK5. The SDK6 includes the GAP_ROLE_ALL, so it’s really straight-forward to implement this use case.

To answer your question, in case of DA14580 and SDK5, to implement a role switching you should invoke a GAPM_RESET_CMD command and reconfigure the device. Please check some related previous forum threads:
