[OTA] Sending Concatenated OTA Commands

[Christopher Burke]

Hi All, I was wondering how I would go about setting the UDH parameter to send concatenated OTA commands. Currently, I set the UDH to 02 70 00 (%02%70%00) however it is my understanding that for concatenated SMS each message needs to be assigned a message part, i.e. 05 00 03 XX 0N 0n where: 05: UDH Length 00: IEI, Concatenated Short Messages 03: IE Data Length XX: Reference Number 0N: Number of Short Messages 0n: Sequence Number of the current Short Message I am going to go on a whim, and presume it should be something like: 09 02 70 00 05 00 03 XX 0N 0n or 08 70 00 05 00 03 XX 0N 0n (%09%02%70%00%05%00%03%XX%0N%0n) or (%08%70%00%05%00%03%XX%0N%0n) Any help or advice would be much appreciated!
