Where is the enable method/command in AN5203

[darla14]

Hello ,

I was checking this AN 5203 : https://www.stmicroelectronics.com.cn/resource/en/application_note/dm00528962-teseoliv3f--i2c-positioning-sensor--stmicroelectronics.pdf

on page 16 the main c code is written.

I wanted to know why we are not enabling the Teseo.I mean which method (if I am not able to find) is enabling the teseo or is it like it is default enabled when we power it ON?

I see the code directly inits the I2C and get the data over i2c?

One more question :

HAL_I2C_Master_Transmit(&hi2c1, 0x3A << 1, (uint8_t *)gpgll_msg, strlen(gpgll_msg), 2000)

>> what is 0x3A << 1 here ?

Is it the Teseo 7 Bit address?

one last question : Where Can I get the information on enabling and getting the similiar data (liek where can I find the list of all NMEA COmmands and thier corresponding commands like this : static const char *gpgll_msg = "$PSTMNMEAREQUEST,100000,0\n\r"; )

Many Thanks in advance !

I2C here using 7-bit, STM32 expects these in the high order bits, so shifted there.​

Thanks @Community member​ 

regarding enable what data should be sent to i2c?

Is there a raw command set available? for enable,configuration and retrieving data?

I am on arduino thats why asking in terms of raw data.

Thanks,
