LoRaWAN ® Multi-Package Access Protocol Specification TS007-1.0.0 ©2022 LoRa Alliance ® Page 8 of 15 The authors reserve the right to change specifications without notice. All multi-package uplinks (fragmented or not) on FPort 225 SHALL end with a Command 226 Token field. The Token subfield SHALL copy the Token value of the last valid command 227 set received. An example of fragmented ANS buffer transmission is provided later in this 228 document. 229 230 The server MAY request the retransmission of any part of the buffer using the 231 MultiPackBufferReq command described in the next section of this document. 232 233 The ANS buffer and Command Token field SHALL be kept in memory until a new multi- 234 package set of commands is received, to allow on-demand retransmissions. 235 236 The size of each command answer payload SHALL be derivable from the command being 237 answered, so that the server can identify the next command byte, if present, or the message 238 end is reached. 239
