GNSS positioning

Hello,I am able to receive data normally when connecting USB with Teseo Suite, but when I connect using Terminal software, there is no data output at all. I am sure the baud rate is 460800. Is there a specific command I need to input for it to start outputting data?I am using "Teseo EVB".The connection with Teseo Suite is normal, and the data output is also normal:However, when I use Terminal software to connect, there is no data output at all:Is there a specific command I need to input for it to start outputting data?Thank you.  

Hello community users! There is a question that needs to be asked. Any help would be greatly appreciated! We want to know Can S2_LP UHF module receive the differential correction data generated by our own gnss base station? So we'd like to know the supported protocols as well as a description of the format. Can S2-LP support transparent protocol? We need to use the tuning method + baud rate + bandwidth that it supports.

Hello,How can I check that the teseo correctly receives L5 band satellite and not only L1?Is it indicated in a NMEA message?Best regardsMich

Hello,In document UM3009 §7.3  =>Multi-constellation firmware supports the following constellations: GPS, GALILEO, GLONASS, BEIDOUand QZSS. All constellations cannot be enabled at the same time, allowed combinations to achievemaximum coverage, are: (GPS+GALILEO+QZSS+GLONASS), (GPS+GALILEO+QZSS+BEIDOU) and(GLONASS+BEIDOU). Any constellation can be enabled as standalone satellite navigation system.Does that means it is impossible to have GLONASS and BEIDOU at the same time? Best regardsMich

Hello,Is there any specific parameters to configure to acheive correct CEP?Starting from default mode I found a CEP worst than some L1 only GNSS....despite I respect the 70x70mm ground plan for the antenna....Many points are correct (but not more) but a few are awfull (more than 20m far away from position...)Do you suggest any ceramic antenna?Best regardsMich

Hello,I updated the teseo liv4f to firmware BINIMG_STA8041_4.6.3.5.3_ARMNow I have the message satellite fault detection:$GPGBS,141053.000,,,,,,,*5DHow can I solve this issue? Afterwards I change the enable constellations. Now I have:$PSTMSETPAR,1227,0x000003c0*05   1 = Current Configuration,$PSTMSETPAR,2227,0xbc000015*53   2 = Default Configuration,$PSTMSETPAR,3227,0x000003c0*07   3 = NVM Stored configuration.Should I write 0xbc000015 | 0x000003c0 inside PSTMSETPAR instead of 0x000003c0? What's more I expected now to have$GN... messages as many constellations are enable but I still have $GP, why?$GPGGA,095248.000,4806.87188,N,0.1,2.1,1.8,2.1*48    => no longitude???? Best regardsMich 

It is unclear to me how to place the Teseo-LIV4F to a low power state. I am a bit confused with the nReset and the Wakeup or Extint pins. In the datasheet, pin 5 is marked as an input and named "WakeUp" and pin 9 is marked as an input and named nReset. Pin 18 is also an input and is named PRG but its description says "Program or WakeUp from DeepStandby. What is DeepStandby?The Teseo-LIV4F has a $PSTMFORCESTANDBY command and the datasheet lists a SW-STANDBY consumption of 10uA with VCC=VBAT=3.3V (which is great for me) but the Hardware Manual says "Teseo-LIV4F offers 1 way of standby: HW standby".What is the best way to enter and exit standby with VBAT at 3.0V and VCC also at 3.0V? Or is it better to just control VCC? 

Hi,How to know the TESEO VIC3DA module work correctly in designed board ?Thank you very much

Hi. I'm currently designing a board that uses Teseo_liv3fl. In its recommended layout and schematic, the components are in 0402 packages and some active components are tiny: BGA824N6E6329XTSA1 and B39162B4327P810. We only solder manually for now as it is still under development stage, and it's been difficult to solder 0402 and the stated active components due to their size. Is it possible to change these components to 0603 and replace the active components with similar replacements without compromising the performance, frequency, etc.? Or changing the packaging will cause impedance mismatch? Link to hardware datasheet: https://www.st.com/resource/en/user_manual/um2980-hardware-specifications-for-teseoliv3fl-stmicroelectronics.pdf

Hi,I am new in TESEO VIC3DA. I have designed a board communication between MCU and TESEO VIC3DA.Does TESEO VIC3DA auto send NMEA sentences to my MCU through uart peripheral ? Thanks

Hi all,I have been doing some experimentation with a LIV4F module and am trying to configure the device for a 5Hz data output rate. I see the device supports up to 10Hz.The commands I have tried via teseo suite are:$PSTMSETPAR,1190,0.2 followed by $PSTMSAVEPAR and $PSTMSRRThe device replies with $PSTMSETPAROK in repsonse to each command, but there is no effect on the observed data output rate.I am sure there is something I am missing when in comes to configuring the device.Thank you for any help.

Hi team,    I already have this module-Teseo-LIV3F( https://estore.st.com/en/evb-liv3f-cpn.html ) But i need communicat the L5 band NAVIC signal. In this module not supported the L5 NAVIC signal.In this module-Teseo-LIV3F( https://estore.st.com/en/evb-liv3f-cpn.html )  replace the L5 NAVIC supported ic a Teseo-LIV4F(https://estore.st.com/en/teseo-liv4ftr-cpn.html)This is supported or Not???Thanks and RegardsAravind.SR

  Hi Team,  i have a query regarding the NAVIC module. Just like GPS module there is made in India navighation called as NAVIC. I wanted to know whether TI can provide me the module or EVT(EVALUATION KIT ) of NAVIC. Thnaks and regards, Aravind.S.R

Hi team ,     How to configer the firmware update for IRNSS and how to create a binary file.Firmware update which software is using?and any breakout board avaliable (Teseo-LIV4F) Thanks and regards Aravind

Hello I am interested at looking at the Teseoo-LIV3F for a application but I require a very fast TTFF. Having read up on the A-GNSS option will this be available any where or any location in the world as long as the server is accessible ?So no matter where you are as long as you can access the A-GNSS server the TTFF speed should improve considerably from up to 35s for COLD START to a few seconds after accessing and relaying the relevant data / information ?. The ephemeris data obtained from the server will be valid for your location and your sky ? thanks cab

hi team,         Any breakout board avaliable for this module(TESEO-LIV4FTR) and sugess the antenna for this module. thanks and regards aravind.s.r

Looking to understand if the new Teseo-LIV4FM will/can support the HAS service by Galileo.  I know the module needs to support the E6 band which I do not see in the product spec for the module.  Hoping that maybe a firmware update may support the band in the future.  Any information is much appreciated.

Hello,I've been trying to implement a positioning sensor using the X-NUCLEO-GNSS1-A1 expansion board using a NUCLEO F401RE, but I am facing problems sending NMEA commands through USART.I am trying to deactivate the NMEA messages using the $PSTMNMEAONOFF,0 and request a single NMEA message using the $PSTMNMEAREQUEST, but the module keeps sending the automatic messages and not responding to the $PSTMNMEAREQUEST command.Do I need to enable some setting for the X-NUCLEO-GNSS1-A1 respond to the commands I am sending via USART?Am I sending it correctly?Thanks in advance,Best regards,João/* USER CODE BEGIN Header */ /** ****************************************************************************** * @file : main.c * @brief : Main program body ****************************************************************************** * @attention * * <h2><center>© Copyright (c) 2021 STMicroelectronics. * All rights reserved.</center></h2> * * This software compone

i am from W-ibeda, which from shanghai.ASM330 which i used for automotive  IMU, now we have some issue and cannot solved, pls. assign sales and FAE to support. our distribute Future cannot support and won/t like to provide ST contact windows to us

Deal all,I borrowed an evaluation board EVBT5MCM to a colleague in order to evaluate the 1 PPS performance over some configurations. I downloaded the Teseo suite software and I saw NMEA messages related to the configuration such as $PTMXXX like. I achieved to change the 1 PPS configuration but I tried the same with the used constellations ($PSTMCFGCONST and $PSTMSETCONSTMASK) with no success and even not possible to get any reply message. I also tried to disable NMEA if that helps to send commands but I lost the NMEA interface. I have checked the offical documentation but I did not find any solution. Please, could anyone to help me in this setup? I checked also that an updated of the firmware could add a particular documentation however I don't have available firmware binaries.Thank you in advance,CheersRaul Nieto

Hello, I use the teseoLiv3 to get the current time with the $PSTMGETRTCTIME command.From experience I wait for the response Time Validity=8(ACCURATE_TIME) to update my embedded RTC.In the documentation there are no details about the different status: Are there more explanations ?Thank you,Pierre

Hi there,I recently got a sample TESEO-LIV4FTR chip.I am used to rtk1010 from locosys, which seems similar in size. Not sure about the specifications. Can this chip also acheive RTK cm level fix using a base or external ntrip server ? Regards,Adrian

"I would like to ask a few questions:Initially, I was able to use the EVB-T5DR, and the NMEA decoding displayed information correctly. However, for some reason, it suddenly stopped working. When I used the UART tool to read the data, it appeared as Garbled code. How can I resolve this issue?Due to the problem mentioned in the first point, I decided to reflash the device, but I encountered a 'sync error' and couldn't flash it.I would appreciate your help with the above two issues. Thank you.

Hi, I'm using TESEO-LIV3F. I  would like to know how to power this device when using the internal battery and how to log data to the SD card.  Sincerely,Aviad

I am working with a Teseo LIV3R and have it up and running in Teseo suite. I would like to modify the configuration but this feature is locked in the software. I have followed the activation instructions but have received no key and no response to emails to the Teseo suite support address. Any help would be appreciated.
