Hi ErnestasB,
Can you please email me directly.
We got RMA'd devices back, still having issues:
Issues/Bugs:
TRB145: Firmware (Latest version)
1) In RS485 Client mode the modem continually drops its connection and reconnects every "timeout interval". It should stay connected as it used to (previous firmwares for TRB145 and other devices like the TRB255 are successful at this).
TRB255: Firmware (TRB2_R_00.02.03.1)
1) In Modbus TCP Slave mode, many of the dynamic registers cannot be read.
https://wiki.teltonika-networks.com/view/TRB255_Monitoring_via_Modbus#Set_Parameters
Basic value registers such as "System Host Name" and "System Uptime" can be read, but the "Modem ID" and most importantly the "IMSI" cannot be read. We need to be able read the IMSI out of the device to identify it. Only about half of the advertised registers are able to be read successfully.
2) In the WebUI, none of the network parameters are filled out - eg, the screen does not show the network that it is connected to, the uptime, the IP address, the IMSI etc. (Screenshot attached)
3) It does not seem to be possible to send AT commands via the CLI (eg. gsmctl -A AT+CIMI should retrieve the IMSI from a BG96 but the CLI says that it cannot understand the command)
4) In the CLI, several (most) of the gsmctl commands are either "not understood" by the interpreter "timeout", or take a very long time to respond (eg. try to get the imsi with gsmctl -x). This still occurs when we put it into debug mode.At this stage it may take >30 seconds for some of these commands to respond, if they respond at all. For the IMSI command, I have only had 1 successful response from this command as 99% of the time it fails. The device has definitely read the IMSI by this time as it is connected to the internet and successfully transmits data over our IPSec tunnel. I have pasted findings from this in blue below:
eg.
root@Teltonika-TRB255:~# gsmctl -v
GSMCTL version: 0.2b
root@Teltonika-TRB255:~# gsmctl -k
root@Teltonika-TRB255:~# gsmctl --at AT+CIMI <-- Dead
root@Teltonika-TRB255:~# gsmctl -x <-- Dead
root@Teltonika-TRB255:~# gsmctl -i <-- Dead
Failed to invoke a gsmd object method
GSMCTL error: reading message
N/A
root@Teltonika-TRB255:~# gsmctl -c <-- Dead
root@Teltonika-TRB255:~# gsmctl -v
GSMCTL version: 0.2b
root@Teltonika-TRB255:~# gsmctl -j
Connected
root@Teltonika-TRB255:~# gsmctl -J <-- Dead
root@Teltonika-TRB255:~# gsmctl -P <-- Dead
We have also had issues with updating and rolling back firmware and had to have TRB145 devices RMA'd as they were irrecoverable.
Let's hope they resolve these issues and the firmware update issues very shortly.
Kind regards, SD
