Android USB probe failing in some SAGEMCOM meters

Forums
Gurux.Serial

Hi,

I have some problems reading specific SAGEMCOM meters.

My Android app can read meters with a Bluetooth probe and with a USB serial probe.
BT probe readings are implemented with a third part library that works fine, and I can read all meters I tried (even these SAGEMCOM I am talking about).

On the other hand, USB probe readings are implemented using GURUX Android Serial library. The problem here is that there are some SAGEMCOM that when I tried to read Profile Generic OBIS "1.0.99.1.0.255" which is hourly readings.

Gurux.Serial

Hi,
I connected the CM-LTE-3 modem to the PC through RS485-USB converter. I set Gurux with the parameters:
-Iskraemeco
-HDLC
-Authentication none
-Client Address 46 (30+16)
-Logical Name Referecing on
-Physical Server 11
-Logical Server 1
-Serial COM4 9600 8N1
-DLMS standards
But the MT880 doesn't answer me. "Failed to receive reply from the device in given time".

Baud rate 115200 for the CH34x chip

Forums
Gurux.Serial

Hello! I apologize in advance for my English.

I’m starting a new project and plan to use your library for serial communication. However, the chip I need to use is the CH34x with a baud rate of 115200, and I couldn’t find support for this configuration. Will your library support this baud rate in the future?
