As part of our Wi-SUN solution evaluation, we are exploring various options including TI. Currently, we have a non-TI Wi-SUN border router that we are considering alongside a TI Wi-SUN router. While the non-TI border router is able to detect and initiate communication with the TI Wi-SUN router, it encounters difficulties during the authentication process. Despite ensuring that the correct certificates are included in the source code of the TI Wi-SUN router, we are still unable to establish a successful connection. Kindly see the logs below from the border router.
