Hi
Just assembled a new PCB with the CC3000MOD from TI. I've used LSR TIWI earlier.
When running same software on both boards, the CC3000MOD behaves strangely.
Logging with wireshark shows strange behaviour. I get retransmitted packets and duplicate ACK's. Also everything is kinda slow.
Both Wifi modules have the latest patch installed.
Is there anything I should be aware of regarding the CC3000MOD?
