# Firmware Updates over the Air via LoRa: Unicast and Broadcast Combination for Boosting Update Speed
## Appendix A Format of the Frames of the Unicast Implementation
### Other Control Frames Sent by the Gateway  
* _OTA STATUS REQUEST_, _TYPE_ = 0x09. An example is shown in Figure 11.
* _OTA FLASH NEW VERSION_, _TYPE_ = 0x0A. The gateway tells the node to flash the new firmware that is stored in its flash memory. An example is shown in Figure 12.
* _OTA REST REQUEST_, _TYPE_ = 0x0B. The gateway tells the node to set to 0 the counters of binary and checksum fragments. The node must answer with an _OTA RESET CONFIRMED_ message. * [PERSON] et al.
