17.2 Notes and cautions to be taken on using remote program update

1. This feature is ONLY for updating new Maestro Smart Pack program. Do not use it for downloading other

things. Always contact Maestro Wireless or distributor for correct update file and information.

2. If you want to perform update for modem at remote site by AT command over SMS, make sure the feature is

enabled by command AT+SMSAT=1 is entered.

3. Make sure you have setup GPRS settings by AT+IPGPRS command. When entering AT+FTPDOTA command the

program will make GPRS connection automatically if not connected before.

4. It is recommended to stop other Maestro Smart Pack’s features such as AutoTCP/UDP connection during program

downloading and updating.

5. Depending on the file size and network condition the download time could be a few minutes up to 3o minutes. Be

patient to wait for response after entering AT+FTPDOTA command.

6. Do not use “~” character on filepath because it cannot be transferred correctly over SMS.

7. No resume function on FTP downloading. The whole file has to be downloaded at one time otherwise the

downloaded data will be discarded

8. If you perform update by entering AT+FTPDOTA command over TCP Terminal (see Chapter 9), make usre you

have set <timeout> value of +TCPTERM command to a large value e.g. >50000, to avoid TCP Terminal closed

during downloading process.
