+ *
+ * Status Packets
+ * ==============
+ * The BedJet protocol depends on registering for notifications on the esphome::BedJet::BEDJET_SERVICE_UUID
+ * characteristic. If the BedJet is on, it will send rapid updates as notifications. If it is off,
+ * it generally will not notify of any status.
+ *
+ * As the BedJet V3's BedjetStatusPacket exceeds the buffer size allowed for BLE notification packets,
+ * the notification packet will contain `BedjetStatusPacket::is_partial == 1`. When that happens, an additional
+ * read of the esphome::BedJet::BEDJET_SERVICE_UUID characteristic will contain the second portion of the
+ * full status packet.
+ *
+ * Command Packets
+ * ===============
+ * This class supports encoding a number of BedjetPacket commands:
+ * - Button press
+ *   This simulates a press of one of the BedjetButton values.
+ *   - BedjetPacket#command = BedjetCommand::CMD_BUTTON
+ *   - BedjetPacket#data [0] contains the BedjetButton value
+ * - Set target temp
+ *   This sets the BedJet's target temp to a concrete temperature value.
+ *   - BedjetPacket#command = BedjetCommand::CMD_SET_TEMP
+ *   - BedjetPacket#data [0] contains the BedJet temp value; see BedjetStatusPacket#actual_temp_step
+ * - Set fan speed
+ *   This sets the BedJet fan speed.
+ *   - BedjetPacket#command = BedjetCommand::CMD_SET_FAN
+ *   - BedjetPacket#data [0] contains the BedJet fan step in the range 0-19.
+ * - Set current time
+ *   The BedJet needs to have its clock set properly in order to run the biorhythm programs, which might
+ *   contain time-of-day based step rules.
+ *   - BedjetPacket#command = BedjetCommand::CMD_SET_TIME
+ *   - BedjetPacket#data [0] is hours, [1] is minutes
