Hello,I recently made a custom PCB with the teseo-liv4ftr for an avionic and i have trouble making it work. The module responds to the nmea commands via I2C, but I couldn't get a fix whatsoever and not even a signal on the PPS pin.The Teseo is solder...
Hi to everybody,I have a annoying problem with Teseo-liv3f (on Astra1B). It can not find any sattelites. What I have:1. Chip is build in dev kit from STM Astra1B, so there is no problem with layout, wrong antenna, etc. 2. I'm using as reference hex f...
I have connected X-STM32MP-GNSS1 with my STM32MP157F-DK2 board. I have connected it directly to serial COM port on windows to use Teseo-suit. I updated the firmware for TESEO-LIV3FL to STA8090_4_6_15_1_CP_LIV3FL_UPG48 by using Teseo-suit. I still can...
Hi there, We are troubleshooting an issue with our module where the GPGGA return shows no satellites detected. We have verified our circuitry according to the hardware instructions document on ST's website - https://www.st.com/resource/en/user_manual...
Hello,I noticed an inconsistency between standard NMEA output and proprietary ST messages.In the log below, $GNGSA reports satellite ID 70,86,71:$GNGSA,A,1,70,86,71,,,,,,,,,,94.9,94.9,1.0*20 But a few milliseconds later, the proprietary messages repo...
Hi All,please point me to sources aboutESD sensitivity in practical applicationsstandard practice to protect RF inputsfor GNSS modules like Teseo LIV4F, LIV3F, with external antenna - this means, the device has a RF connector (MCX, SMA) which might b...
We recently had a batch of equipment assembled with the Teseo-LIV4F instead of LIV3, and I'm running into some real strange behaviour.Whenever I try to disable the GPGSV frame the whole NMEA output breaks. It is not a problem with the receiving host ...
Hey!I updated the firmware to the ME version, I am receiving some RTCM messages, but only a limited amount shows up in the message monitoring, also nothing can be decoded. Is there any documentation available on how to configure which RTCM messages s...
Hello,I see that the LIV3FL can enable the PSTMPV message, which includes 3D velocity data. The equivalent setting does not seem to be available for the LIV4F. Is this correct? Is the LIV4F unable to provide 3D velocity data?
Unfortunately we experienced some serious issues with the Teseo-LIV4F regarding custom configurations on the CDB-ID 201 register.While the issue with broken NMEA output seems resolved by disabling I2C (See other topic)https://community.st.com/t5/gnss...
