aErr drainUEI(const uint8_t option)

Drain all packets matching this UEI from the packet fifo.

This functionality is useful in rare cases where packet synchronization is lost and a valid return packet is not accessible.

aErr setStreamEnabled(uint8_t enabled)

Enables streaming for all possible option codes within the cmd and index the entity was created for.

  • enable – True - installs/updates callback and ref; False - uninstalls callback

  • cb – Callback to be executed when a new packet matching the criteria is received.

aErrNotFound - Item not found (uninstalling only)

Returns:

aErrNone - success

aErr getStreamStatus(std::map<uint64_t, uint32_t> *status)

Gets all available stream values associated with the cmd and index of the called API. Keys can be decoded with Link::getStreamKeyElement.
