Good day. Thank you for your question.
The SMS/GPRS command to perform a soft reboot is cpureset. For more information on the SMS/GPRS command, please refer here - https://wiki.teltonika-gps.com/view/FMB120_SMS/GPRS_Commands
With login and password : <login><space><password><space>cpureset
Without login and password : <space><space>cpureset
If you are sending via GPRS then you may skip the login, password, and <space>.
This is, however, not recommended to be sent to the device every hour/over a constant interval as the device refreshes and works normally without a reset. But if you are facing any issue which leads you to reboot the device at a specific interval/regularly to work normally then we would need to analyze the issue. In this case, please reach out to us via VIP Helpdesk or contact your Sales Manager/Distributor. If you don't have any contacts with our Sales managers, please contact them on our official website https://teltonika-gps.com/ and click on the "Contact Us" button. When you will click, please fill out the form and submit it.
Note: as a topic, please choose "Vehicle telematics" or you can send an e-mail with the description of your situation to email@example.com
Thank you in advance.
