Hello, Daniel,
Hope you are doing well,
In order to solve your issue we would like you to clarify few points.
1. Are you sure you want to read log files? Log files are saved in .log format. They are used for debugging and to inspect processes, commands that device is executing.
You can receive log files remotely with a help of "hercules" application, by sending special command you will be able to receive logs. SMS command used to set up log sending to server. “SMSlogin<space>SMSpassword<space>log2srv<space><enable>,<mode>,<APN>,<username>,<password>,<IP>,<port>,<TMO>,<Log mode>” ,
To initiate start of log use command “SMSlogin<space>SMSpassword<space>log2srvstart”
To initiate stop of log use command "“SMSlogin<space>SMSpassword<space>log2srvstop”
When using "hercules" to receive logs make sure FMB630 device is not sending data to a specific server, so it would not disrupt logging.
More detailed information can be found in the user manual of FMB630 device, page 164: https://teltonika.lt/downloads/en/fmb630/FMB63_User_Manual_V1.10.pdf
2. .Rec files are records that are being sent to server by your device and are used to read specific I/O parameters plus data sent by device that are all placed in AVL packet. Are you sure that you require to read .Rec files?
Best regards.
