DHCP not working

Under certain conditions the Series 3 JNIORs are not able to obtain IP addressing via DHCP. This is due to a flaw in the early implementation of IPv6, The bug is part of the built-in TINI operating system supplied by the component manufacturer and INTEG is not able to directly correct it.

You can disable the use of IPv6 by making the call to com.dalsemi.tininet.TININet.enableIPv6 with a ‘false’ boolean parameter. As this would require a change to the OS release and the product being no longer in production and deprecated, the recommendation is to disable IPv6 on the local subnet or use a fixed IP address. Since a fixed IP address is usually required and few JNIORs actually use DHCP the OS update is not scheduled.

Alternatively an application can be set to run on boot that makes the call.
