Hello,I've made a custom board populated with a LIV4FM module and many other components.The LIV4FM communicates through a USART with a STM32U5 correctly but do not find any satellite.Here are questions :I use a patch antenna. It is connected to the L...
Tesla’s GNSS antenna design is already more advanced than many people realize.My 2026 Model 3 Performance appears to use a much more sophisticated GNSS antenna — a spiral PCB structure — rather than the older small ceramic patch antenna design. Toget...
I am trying to check RTCM and NMEA data on the EVB-T5MCM, but I have encountered the following issue.When I run Automatic Port Detection in Teseo Suite v7.6.3, I can only see RTCM data. I tried adding NMEA by selecting the NMEA checkbox in the config...
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...
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...
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 ...
