I know that the OL2385 can run the SigFOX stack, so now problem with this. However, is it possible that in my application, I could bypass the SIGFOX stack and use the OL2385 as a normal FSK radio, running my propriety protocol. Reason I need this is for a fallbcak should the SIGFOX network go down... I don't want to have a separate radio chip as my fall back option, so would like to do both on the same OL2385.
