Teseo Vic6a not responding after parameters change
Hi,
I am developing software for a GPS tracker based on the TESEO VIC6A module. Our goal is to achieve the highest possible fix rate.
I was able to establish communication with the module via UART0 using the ST/NMEA protocol. After that, I started modifying the firmware configuration to improve performance. I sent several PSTMSETPAR commands and received PSTMSETPAROK responses for all of them.
However, I did not observe any changes in the module's behavior. I then attempted to save the modified parameters to non-volatile memory using the PSTMSAVEPAR command and received what appeared to be a successful response. Despite that, the module still behaved exactly the same.
The last command I sent was PSTMSRR. Since then, I have been unable to communicate with the module. I have tried all available combinations of baud rates and flow control settings without success.
The parameters I attempted to modify included:
increasing the UART baud rate,
enabling a higher fix rate,
customizing NMEA output lists 1 and 2.
Does anyone have experience with this module? Is there any way to restore or reflash it?
I looked into Teseo Suite, but unfortunately this module is not yet supported. I have access to professional electronics and debugging equipment, so I could connect a debugger/programmer if necessary. However, I do not have a firmware binary or any image that could be used to restore the flash memory.
Any advice would be greatly appreciated.
Thank you in advance
