We bought some logomatic some few weeks ago, and we are trying to use them to log some data from our sensors.
Unfortunately, we are meeting some problems to log data over a long period of time (more than 9 hours).
Our sensors are sending 3 bytes to the logomatic v2 card every 312.5 µs at 115200 bauds. We also tried the 57600 baud rate to send periodically the 3 bytes to the logomatic.
When the system is working after a long period of time (eg. 9 hours), the logger starts missing to log pages of 512 bytes and we don't understand why because it was working well from the start till the 9th hour. Whatever the baudrate is, we have the same behavior (missing of 512 bytes pages).
We did our tests on a lab power supply, to avoid the discharge problems caused by the battery.
Could you help us understanding why we meet this logging problem with the logomatic, or do you have an idea where in the firmware some modifications could be done to correct this bug ?
Thanks for your help
