Expand description

Reads a downlink on the clock port and acts on it, section 3.2.

§Arguments

  • sync - the package.
  • payload - what arrived on port PAMOJA_LORAWAN_CLOCK_PORT.
  • payload_len - its length.
  • out_correction - receives the seconds to add to the device’s clock.
  • out_has_correction - receives 1 when there was one.
  • out_more - receives 1 when another correction is coming.
  • out_resync - receives how many requests a resynchronization command asked for, or 0.
  • out_answer_due - receives 1 when the device now owes an answer.

§Returns

PamojaStatus::Ok on success. Every out pointer may be null.

§Errors

Returns PamojaStatus::Codec for a message this package cannot read.

§Safety

sync must be a live handle, payload must point to payload_len readable bytes, and every non-null out pointer must be writable.
