* \brief A data strcuture representing the radio's primary mode of operation
|
|
*
|
|
* The CC13xx / CC26xx radio supports up to potentially 3 modes: IEEE, Prop and
|
|
* BLE. Within Contiki, we assume that the radio is by default in one of IEEE
|
|
* or Prop in order to support standard 6LoWPAN / .15.4 operation. The BLE
|
|
* mode interrupts this so called "primary" mode in order to send BLE adv
|
|
* messages. Once BLE is done advertising, we need to be able to restore the
|
|
* previous .15.4 mode. Unfortunately, the only way this can be done with
|
|
* NETSTACK_RADIO API is by fully power-cycling the radio, which is something
|
|
* we do not want to do.
|
|
*
|
|
* Thus, we declare a secondary data structure for primary mode drivers (IEEE
|
|
* or Prop). We use this data structure to issue "soft off" and "back on"
|
|
* commands. Soft off in this context means stopping RX (e.g. the respective
|
|
* IEEE RX operation), but without shutting down the RF core (which is what
|
|
* NETSTACK_RADIO.off() would have done). We then remember what mode we were
|
|
* using in order to be able to re-enter RX mode for this mode.
|
|
*
|
|
* A NETSTACK_RADIO driver will declare those two functions somewhere within
|
|
* its module of implementation. During its init() routine, it will notify
|
|
* the RF core module so that the latter can abort and restore operations.
