A very strong talk recommendation from #38c3:
https://media.ccc.de/v/38c3-beyond-ble-cracking-open-the-black-box-of-rf-microcontrollers
Despite the very unassuming name talking about "BLE", this talk is about something much more interesting:
Reverse engineering the Cortex-M0 RF coprocessor and engines in the TI CC13xx radio chipsets!
Those chips are basically little I/Q SDRs with a bunch of hardware offloading. TI keeps all of this hidden away very nicely -- but now they've built tooling to work with that CPU core & RF offloading directly.
