Expand description

Builds the wake-on-radio frame ahead of a Class A uplink, TS011-1.0.1 section 5.3.2.

The uplink’s carrier is encrypted under WorSEncKey with a block that folds in the frame’s own carrier and counter, and the frame is signed with WorSIntKey.

§Arguments

  • keys - the device’s keys.
  • dev_addr - the device’s address.
  • wfcnt - the WOR frame counter, which the device raises for every WOR frame it sends.
  • uplink - where and how fast the uplink follows.
  • wor - the carrier this WOR frame goes out on.

§Returns

The frame.

§Errors

Returns LorawanError::MalformedFrame for a data rate past 15 or a frequency the three-byte field cannot carry, in either carrier.
