Issue:My startup script will sometimes fail and sometimes hang because of the script attempting to IPv6. My current scenario is a static IPv4 from my internet provider. After several attempts to connect to IPv6 I either get a failure and then the modem hangs up or the script just sits and hangs and doesnt’ every close. I have disabled IPv6 on the entire Raspberry Pi via /etc/sysctl.conf.
I don’t see anything in the rak2013 specifically stating IPv4 or IPv6 but I would love to find a way to only attempt IPv6 and then close the connect script successfully.
Any thoughts on this?
