dflet 0:305844973572 54 The TI library calls this routine when asynchronous events happen.
dflet 0:305844973572 55
dflet 0:305844973572 56 For example you tell the CC3000 to turn itself on and connect
dflet 0:305844973572 57 to an access point then your code can go on to do its own thing.
dflet 0:305844973572 58 When the CC3000 is done configuring itself (e.g. it gets an IP
dflet 0:305844973572 59 address from the DHCP server) it will call this routine so you
dflet 0:305844973572 60 can take appropriate action.
