This can cause synchronization of the DIS messages and problems in larger networks, ref 2a2175a2149e0a11af0fb5dfb514a3e5d182f46d. \r\n\r\nI see there is some true RNG implementation in the driverlib, but I am not confident enough on it to create a pull request atm.\r\n\r\nRegards,\r\nAndreas"},"comment":{"url":"https://api.github.com/repos/contiki-os/contiki/issues/comments/137600735","html_url":"https://github.com/contiki-os/contiki/issues/1238#issuecomment-137600735","issue_url":"https://api.github.com/repos/contiki-os/contiki/issues/1238","id":137600735,"user":{"login":"g-oikonomou","id":705207,"avatar_url":"https://avatars.githubusercontent.com/u/705207?v=3","gravatar_id":"","url":"https://api.github.com/users/g-oikonomou","html_url":"https://github.com/g-oikonomou","followers_url":"https://api.github.com/users/g-oikonomou/followers","following_url":"https://api.github.com/users/g-oikonomou/following{/other_user}","gists_url":"https://api.github.com/users/g-oikonomou/gists{/gist_id}","starred_url":"https://api.github.com/users/g-oikonomou/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/g-oikonomou/subscriptions","organizations_url":"https://api.github.com/users/g-oikonomou/orgs","repos_url":"https://api.github.com/users/g-oikonomou/repos","events_url":"https://api.github.com/users/g-oikonomou/events{/privacy}","received_events_url":"https://api.github.com/users/g-oikonomou/received_events","type":"User","site_admin":false},"created_at":"2015-09-03T23:28:11Z","updated_at":"2015-09-03T23:28:11Z","body":"We need a `random.c` that implements `random_init()` and `random_rand()`.
