Please be informed that the latest FW TRB1_R_00.07.04 is implemented successfully.
And all the recommendations and commands (cat /dev/rs232) that were given by you above and were carried out, but without result.
What other commands can be given to make sure again?
A completely different question: for communication, we use a SIM card from an operator with a static IP. If the ability to use a usual internet SIM card from the operator? But at the same time, when the modem is turned off and on at the far end (besides to the electr. meter), then the IP will change and it will be impossible to provide communication without knowing the IP. Is it possible, taking into account the latest version, to set parameters, for example, to make a connection by MAC address? If possible, please describe in detail what parameters need to be set on the modem in order to implement a connection to the modem.
Thank you in advance.
Waiting your response.
