Hello,
I have designed some PCB with uBlox modems and GNSS (precisely Lara6004 and MaxF10). As nobody can say that Trasna will continue to produce uBlox modems, I’m trying to do a new design and I have a simple question.
In WP76XX Product Specification r12.pdf (PP. 102 and 103), I can read that WM7607 module can drive an external i2c slave. But I’m unable to find more information. Can I connect a GNSS to WP7607 and how can I send data to this i2c slave ?
Best regards,
JB
i saw there are i2c related commands in console:
Thanks for your answer but I’m not sure I understand.
uBlox modem uses AT commands to access to GNSS through i2c bus.
In my design, I only have a RS232 interface (1,8V, 8 lines). I beleive that console is available on second UART. Can you confirm that i2c slave is only accessible through UART2 ?
Regards,
JB
the linux console can be accessed by UART1 and UART2, it depends on what you set in AT!MAPUART? in the WP76 module
In addition, the USB ECM interface can also accept SSH from the host so that you can login to the linux console to access i2c.
OK. Unusable in my case. As modem is installed behind a SPI/RS232 bridge, I will add a second one to access to GNSS module through RS232 also.
Best regards,
JB
actually you can consider to write a legato application in WP76 module so that it can accept some custom AT command and run some custom code inside the application.
Here is an example to implement a custom AT command AT+KHTTPCFG and print out the parameters:
