Hello ,

in the document : https://www.stmicroelectronics.com.cn/resource/en/application_note/dm00528962-teseoliv3f--i2c-positioning-sensor--stmicroelectronics.pdf

STM32_Nucleo64_F401RE_FirmwareUpdateI2C.bin > for getting NMEA data from GNSS to Host controller over i2c

STM32_Nucleo64_F401RE_FirmwareUpdateUart.bin > for getting NMEA data from GNSS to Host controller over Uart

STM32_Nucleo64_F401RE_I2CBridge.bin > ?

STM32_Nucleo64_F401RE_UARTBridge.bin > for getting NMEA data from hostcontroller to PC over serial UART

Not getting the use of the bold bin(STM32_Nucleo64_F401RE_I2CBridge.bin). Is the understanding for the rest correct?

STM32_Nucleo64_F401RE_FirmwareUpdateI2C.bin > for getting NMEA data from GNSS to Host controller over i2c

>> is the below set of commands does the same - enable the GNSS for fetching data from GNSS to Host controller over i2C?

$PSTMCFGMSGL,3,1,0,0 $PSTMSETPAR,1227,1,2 $PSTMSAVEPAR

in that case what should be the default fw flashed on the GNSS(is UART or I2C)

please clarify

best

Hi

STM32_Nucleo64_F401RE_FirmwareUpdateI2C.bin

is the stm32 driver to have firmware update working on stm32 and LIV (when connected over I2C)

STM32_Nucleo64_F401RE_FirmwareUpdateUart.bin

is the stm32 driver to have firmware update working on stm32 and LIV (when connected over UART)

STM32_Nucleo64_F401RE_I2CBridge.bin > ?

is the stm32 driver to have NMEA working on stm32 and LIV (when connected over I2C)

STM32_Nucleo64_F401RE_UARTBridge.bin

@Francesco Virlinzi​  Thanks for answer ,

for case :

STM32_Nucleo64_F401RE_I2CBridge.bin > ?

is the stm32 driver to have NMEA working on stm32 and LIV (when connected over I2C)

do I need to send the below command as well to enable it for i2c??

$PSTMCFGMSGL,3,1,0,0 $PSTMSETPAR,1227,1,2 $PSTMSAVEPAR

if No , what is the prec ondition for the gnss to support this command(in terms of fw flashed)

Br,

Pv
