recently i am testing my fmb640 in remote mining area, where there are several GSM signal blind spot
I have set the parameter in configurator to send record to microSD , and set record setting after position fix
As i know, the device will create record data wether there is GSM signal or not since there is record period and send period (min. send period 1)
But in the platform i used (Gurtam wialon) it seems that the device only send record when there is a GSM signal, it didn't send any previous unsent record
The possible problem in this case is my device setting in configurator or setting in web platform when recieving data
Does someone here have any similar problem and could help with my problem ?
