Interface and connectivity ICs

In the UM3475 at page 10 it says "Mission 2 mode (LwIP running in ST67W611M1)".I think it should be "Mission 2 mode (LwIP running in STM32)".

Hi, We have two ST60 eval boards and we are trying to configure them for test.  The boards arrived with no documentation, and there are a lot of jumpers that we can set.  We are trying to get either a user manual for hte board or the schematics so we can determine what we need to set / configure in order to get it operational. Thank you,WillST60 Eval Board

As EMIF06-MSD02N16 Is approaching EOL by 2029, Can you please provide alternate part for EMIF06-MSD02N16. We are planning to design SD card interface and were considering this part for our new design. if you have any alternate part equivalent to EMIF06-MSD02N16, kindly suggest the alternate part with EOL status.

Hello, I am using the x-nucleo-67W61M1 and the supported STM32N6 nucleo and I run the HTTPS Server application. The sample works well. I want to transfer loads of data and I do it through cJSON. I understand that i need to set a different get command and add an if statement in the HTTP_process_response that will handle the request and it will respond accordingly. I have set also a script in Matlab that does continuous gets and after a while i see that the STM is stuck and is no longer responding (I have the LEDs toggling in a different RTOS task) the log when that happens is:[ERROR] [114031] [HTTP_00000001] (w61_at_net.c:441) W61_AT_SetExecute: W61_STATUS_TIMEOUT. It can lead to unexpected behavior.

Hi everyone, It is clear that S2-LP based 868 Mhz has a serial sniffer stack ready to work in MX/IDE. I would to validate communication a communication on 433 Mhz the same way. But the corresponding development board https://estore.st.com/en/steval-fki433v2-cpn.html is not listed in the MX projects example. Is there any chance it is working as it does with the 868 Mhz ? Best regards,

The page https://wiki.st.com/stm32mcu/wiki/Category:Wi-Fi provide lots of links that give a page not found error:https://wiki.st.com/stm32mcu/wiki/Connectivity:Interfacing_a_Host_with_the_ST67W611M1https://wiki.st.com/stm32mcu/wiki/Connectivity:Regulationcertificationhttps://wiki.st.com/stm32mcu/wiki/Connectivity:ST67W611M_AT_Command_v1-0-0

Hi,I am testing the new X-NUCLEO-67W61M1 with the NUCLEO-H7S3L8 for the purpose of sending data over WiFi and BLE. For reference, I am using the STM32CubeIDE.However, I have followed the guide in the software package for the X-NUCLEO-67W61M1 in Github (link https://github.com/STMicroelectronics/x-cube-st67w61/tree/main/Projects/NUCLEO-H7S3L8/Applications/ST67W6X/ST67W6X_CLI ) and when I try to send commands with Tera Term with the recommended settings, I see no output in the terminal.I can see that the X-NUCLEO-67W61M1 is working and correctly identified when flashing the NUCLEO-H7S3L8 with the NCP_update_mission_profile.bat file (which for some reason I could only find in the software package provided directly on the official ST site https://www.st.com/en/embedded-software/x-cube-st67w61.html). I have also tried flashing the NCP_update_mission_profile_t01 and NCP_update_mission_profile_t02 from the Github software package but I still see nothing

HelloI have a problem with the P2P Project which I set up with stm32F401RE and the x-NUCLEO-S2868A2 radio shield. The project attached is actual an a little bit extended Version of the P2P example, I just modified the shield and added R17 to see the radio led blink. I commented out my printf and defined some not used GPIO pins.Debugging my project (attached) just shows the act not as it should. Calling MX_X_CUBE_SUBG2_Init just jumps to MX_SUBG2_P2P_Process. What do I miss? I mean a processor should behave deterministic but what I see is just random.What makes me suspicious, is that any RSSI relateted functions are commented out in the generated app_x-cube-subg2.c. And some people in the forum mention a problem with RSSI.I would really appreciate if someone could look on the code and give me a hint.Tobias Badertscher

Hello, I implemented a project using STUSB4700 to provide a charge to an Android tablet, the power interface is resolved using this topic https://community.st.com/t5/others-hardware-and-software/stusb4700-constant-output-switching/m-p/734155  because I had the same problem in the first time because I used some 5v for source, but now the power is resolved and I've the second issue, in parallel I use the USB C to communication by USB-serial converter by Android Tablet, but the converter isn't recognized by android, I try found in this document: https://community.st.com/t5/interface-and-connectivity-ics/stusb4700-4710-i2c-register-details/td-p/234334?attachment-id=8852 the register to set the accessory interface in negotiation by CC channel but I didn't have success, can you help me?In attach my schematic. Best Regards.

Hello, I have a circuit where a STUSB4500 USB-PD controller is connected with ESP32 via I2C.The problem is that when a USB cable is connected and STUSB4500 powers up, the whole I2C bus clock slows down to 1 kHz which is too slow. After the ESP32 is reset, the device works correctly.This slow-down also happens when the USB cable is disconnected.The ESP32 is battery powered, so it is already running when USB is connected. The STUSB4500 is only powered from USB, so it is without power when the cable is connected.The communication and PDO setting is working correctly (sparkfun library is used) Do you know what could be causing this?

Posted on March 14, 2018 at 10:23I am using STWPLLSim tool to simulate loop values for STW81200. After installing, when I start the program the following LIBRARY NOT FOUND error occurs:java.lang.UnsatisfiedLinkError: C:lProg ram Files (x86)1STMicroelectronicsISTWaLSim_v5.31Loaderltimeresp.d11: Can't find dependent librariesAnybody has solve this problem?

Is it feasible to use the ST8500 + STLD1 configuration for modulating, demodulating, and amplifying signals, then coupling them via high-voltage film capacitors onto a cable powered by DC140 for communication? Are there any better solutions or suggestions? Thank you. *This post has been translated from Chinese to comply with the ST Community guidelines.    

I'm trying to develop a multiprotocol board with Dual Stack wM-Bus + NB-IOT. I found this link:https://www.st.com/en/wireless-connectivity/nb-iot-products.html So the ST87M01 module is capable of it. I have the next questions:1) The module is sold with the firmware (dual stack) flashed ?2) The module need extra hardware? It is a noise filter or something, or it just need a STM32L5 as a host?3) Where can I find documentation about how to control the ST87M01 module from the host? An AT command list or something. Thanks!

How do I connect to the X-NUCLEO-67W61M1 uart in order to access the 'AT' commands?I never get the AT> command prompt, although I get the bootup output spew, see below sample. I have tried 2 different uart-to-usb interface boards that work on other systems, so I have confidence in them.The commands are documented here: http://wiki.st.com/stm32mcu/wiki/Connectivity:ST67W611M_AT_CommandMy setup uses the X-NUCLEO-67W61M1 expansion board with the Nucleo-H7S3L8 host board, and I successfully built and run the ST67W6X_CLI sample application. Both boards have the default configuration for the solder bridges. I know I can use the CLI sample app for 'AT' commands, but that is through the host board, and not what I am asking.I have also been able to connect a serial interface interface to the TX & RX connectors at either the CN7 or CN9, on the X-NUCLEO-67W61M1 and get the bootup output on my terminal emulator. Contrary to the documents I could find, I had to use baud r

Dear All,I am waiting for the availability of the x-Cube-ST67W61 package update to version 1.1.0 which is available on GitHub but doesn't show up in CubeMX at the moment. Do you know when it will be available via embedded package update?Best regards,Peter 

Hello Community experts, I am working on my company's new product line designing about 10 products. We are planning to use S2-LP transceiver for 868MHz and 915 MHz devices. For at least 2 products, we need as long range as possible. Since the Half Wavelength dipole antenna has the highest radiation efficiency, we are evaluating this type on PCB antenna. As we all know, dipole antenna is a balanced (differential) antenna. It can be interfaced with a transceiver with differential input/output. However, the S2-LP has balanced receiver (RXp and RXn pins), but unbalanced output (Tx). We want to use the matching BALUN (BALF-SPI2) made by ST, as this also has built-in harmonic filter. Question: How can I interface S2-LP with a 868-915 MHz dipole antenna? This is the 1st time we are planning to use S2-LP, so I am new to it. I hope someone will give me an answer. Thanks. AB Singh 

Hello, does ST67W61 module support pass-through mode?   I have an application based on a third-party IP stack and it would be a pain to rewrite it all with AT primitives. A far simpler solution would be replacing low-level calls to transmit and receive Ethernet frames over SPI link.   Alessandro

I am planning to have my application interface with the service API of the X-CUBE-ST67W61 Software package. How does the shell utility interface with the Service API? Is the communication interface through a queue?

Hi everyone!We are trying to launch the GFSK reception on S2-LP in the basic mode. We have noticed that by reducing the deviation to 10 kHz most of the received packets gets discarded and even those accepted have at least 2-3 bits of errors. This behavior intensifies as we reduce the deviation even further. Due to the specifics of project FEC, CRC and other channel coding algorithms are not considered. The goal is to understand up to which deviation the reliable reception is possible. S2-LP is tested in pair with certified SDR GFSK transmitter, frequencies are synchronized, RSSI is within the allowed range with good margin.If there are specific register settings that could help to improve the reception quality or you are having similar issues, please let us know by replying to this post.

Dear all， I'm trying to control ST67W611M1 wifi module by using a linux host chip. After flashing the newest firmware I reset the module to SPI mode. Some logs can be received through the uart interface and the SPY_RDY pin is drived to high level. But I just receive 0xAA 0x55 0x09 through SPI, it seems not a 'Ready' signal. I am sure that the SPI is configured as requested, which is confirmed by using a oscilloscope. What should I do to solve this problem? Besides, That would be great if a linux-based SDK can be provided. Thanks

Hello,I wanted to share about the VL53L8CX sensor and it's I2C.I have been using a lot of VL53L sensors (5CX, 1X) and now the 8CX.It always used to work super easily but with the VL53L8CX I cannot seem to make it work. Running an I2C scan doesn't detect anything.I am using an integration board from Aliexpress so I don't know if the problem comes from it but I have seen many posts of people having (I2C) issues with this VL53L8CX and I have not yet seen a solution.My wiring to ESP32-S3 is : VIN = 3.3VGND to GND.SDA to SDA SCL to SCLLPn driven high by GPIO (I tried to wired it directly to 3.3V also)NCS to GND. (I have tried with and without a resistor)SPI_I2C_N to GND. (I have tried with and without a resistor) I do not know if the problem comes with this integration board which I cannot find proper documentation of but otherwise I can only see the board from POLULU which is not as good because it does not allow to use the glass cover. Any help would be appreciate

Hello STM32 Community,I am working on an STM32 project using NanoEdge AI Studio, where I’ve trained models on sensor data and deployed them to my STWINBX1 for anomaly detection. The model is successfully integrated, and now I need to send real-time notifications wirelessly whenever an anomaly is detected.Requirements:Bluetooth (Preferred): I would like to transmit "normal" or "abnormal" status using Bluetooth Low Energy (BLE) and receive real-time notifications on the Android ST BLE Sensor app. How can I achieve this? Are there any examples or libraries available for BLE communication on STWINBX1?Wi-Fi Alternative: If BLE is not the best approach, how can I send this anomaly detection data over Wi-Fi? Are there example implementations for sending real-time alerts via MQTT, HTTP, or another protocol?Since STWINBX1 includes BlueNRG-M2 (BLE 5.0) and EMW3080 (Wi-Fi), I believe there should be an efficient way to integrate wireless communication with my anomaly detection system. Could someo

Hello, I use the ST67W611M1 module in station mode with activated DHCP client. For a generic configuration of my software I want to use the Wifi_GetHostAddr() function to acquire the IP for a given host name. The problem is, that the DHCP client only uses the third DNS Server provided by the Wifi APs DHCP server (see attached picture). The first and second one are always 208.67.222.222 and 8.8.8.8 no matter what I configure. And the DHCP must offer at least three DNS servers. Otherwise the last one would be 0.0.0.0. Sure, I could just setup three DNS servers, but this is a very ugly solution. W6X_WIFI_DHCP is 1. W6X_WIFI_DNS_MANUAL is 0. I tried two different DHCP servers. Is this a firmware bug of the ST67W611M1? Has anyone the same problem? Kind regards Jannis

I want to use the esim ST4SI2M0020TPIFW,  it has an EP, the datasheet doesnt mention if it needs to be connected to ground or not, does anyone know if it needs to be connected?
