Interface and connectivity ICs

Comrades, hello maybe you know, what is this element on the board?how to replace this element.

I am having FKI868V2 with me at the moment. And i would like to know how to set the frequency hopping with S2-LP DK application.​Kindly advise.​

Hello,in our application, we are using STEVAL-STLKT01V1 boards.I ported the BLE Chat application from BlueNRG DK 2.0.2 to STEVAL-STLKT01V1 and I'm able to transfer data between client and server.However, I discovered that data transfer rate is quite slow.The transfer rate for data sent from server to client reaches about 6KBytes per second.But in the opposite direction, for data sent from client to server, I'm getting a ridiculous speed of 160 bytes per second.I'm having difficulties to understand if there are some options in the source code that could change those speeds.How can I regulate the speed of the link in the BLE Chat application?Thank you very much for your time.Sincerely,Carlo Bramini.

Hello,I'm working on the Nucleo-BNRG2A1 board.Starting from the Virtual_COM_Port application in X-CUBE-BLE2 version 3.1.0, I have made modification to work on my L496ZG-P Nucleo Board.When started the BlueNRG GUI 4.0.0, I have the following error popup:"Old DTM fw detected. Update DTM fw."On first test, version given by BlueNRG GUI were the following:BlueNRG-2 HW v1.2BlueNRG FW v2.1 - DTM SPI v3.0.0Motherboard FW v1.6I used BlueNRG-W Flasher Utility with the DTM_SPI.hex file in BlueNRG GUI\Firmware directory to update the board. Now versions are the following:BlueNRG-2 HW v1.2BlueNRG FW v2.1c - DTM SPI v3.2.0Motherboard FW v1.6But I still have the same error popup.Is there anything else I can do to avoid this error? In BlueNRG GUI I tryed the Stack Updater with no succes.Thank youAntoine

I wanted to test one feature for my product where I need to transfer the chunks of data (in Hex) from mobile app to ST BlueNRG2 device.SO wanted to ask do we have such standard mobile app for free which can be used for testing the data transfer between mobile app and BlueNRG2 device?

Hello, I am facing a problem, I am working on BlueNRG-tile (STEVAL-BCN0002V1B). For that I have download the SDK. In that there are so many examples have been given. One of them is BLESensorDemo. Now I want to work with this example. So I need to do some modification in that. And I have open that project in the AttolicTrueStudio. But, It is not able to compile it is giving error like (arm-atollic-eabi-size: 'BLE_SensorDemo': No such file) while building. Can you please let me know that how to solve it?

I have nucleo idb05a2 on board re401. i have compiled sensorDemo_BLEsensor-App. it work with Galaxy bluetooth 5.0 and not work with Honor bluetooh 4.2.Then i change name from "BlueNRG" to "TestBlue" (compiled and write) but still appired "blueNRG" string in bluetooth found devices. how it it possible?

Hi, I am trying to use a X-NUCLEO-BNRG2A1 with a NUCLEO-L476RG .I have used projects of X-CUBE-BLE2 with STM32Cube IDE. When I use sampleApp and SensorDemo_BLESensor-App it work, but Virtual_COM_Port doesn't. The project successfully built and uploaded into the MCU, however no Com port appears and neither does bluetooth, it does not do anything.Even if I copy directly the binary file into the "NUCLEO" device I see in Computer directly without using STM32Cube IDE, it doesn't work.Any help would be appreciated.

When a central device bonds with my peripheral, I check the public address of the connecting/bonding device and store it for later use. I was expecting that aci_gap_get_bonded_devices would return the address of any bonded devices, but the address(es) retrieved by aci_gap_get_bonded_devices do not match the address values of connecting devices. How are you supposed to make sense of the address(es) returned via aci_gap_get_bonded_devices?How can I compare a connecting device's address against the address(es) returned via aci_gap_get_bonded_devices?

Hello everyone,I have a small problem with my shield, the S2LP, when I start a transmission while waiting for an interrupt on my GPIO_0 (interrupt at low state), it sometimes never happens and my timeout is then called after 10 seconds, which is normally good enough to send the whole frame.I made some modifications and after several searches, I noticed that the problem came in part from the change from SDN to 0 (to wake up the S2LP) :In the documentation of the spirit it is stated that I normally have to wait 500us for its wake-up, but here as you can see, yet it has 1.5ms! to wake up.I have some times, problems sending data, but only after I wake-up my board (Nucleo - G070),after a send fail and if my board don't return in the standby mode I can send, what I want.Thanks for reading,Quentin.

I am Enabling Link must be encrypted to read and Link must be encrypted for write , can how we can read and write the data through encryption . if any procedure need to follows , can you share any document related on this .

Hi everyone, I'm working on a project where I interface the micro STM32F746ZGT6 with a CMOS sensor to acquire images. What I wanted to do is then transmit them using an HDMI connector but I don't understand which communication pins of the micro I could use. I only find an HDMI-CEC for control, nothing for parallel transmission. Any solution?

I'm using the BlueNRG-M2 connected to a Nucleo-L031K6 board. It looks like the V1.0 of the BlueNRG-MS software pack isn't compatible with my Nucleo board. I get an error when I try to download the BlueNRG-MS pack. Should I be trying a different one?Is there some page, documentation or tutorial that shows the proper way to get the BlueNRG-M2 project setup properly?Thanks,Richard

Hi, I am new to the BlueNRG family and have been struggling to find the currently recommended development environment. I read that the STM32cube environment does not support it, so I have downloaded the last Atollic version (9.3). This does seem to successfully compile the example BlueNRG projects, but I cannot start a debug session with the STLINK V2, which gives error "Reason: ST-LINK: Could not verify ST device! Abort connection."I have experimented with openocd unsuccessfully (invalid command name "WriteDP").I am however hopeful that I have a valid hardware setup as the BlueNRG ST Link Utility seems to successfully connect to the target).Please can someone advise a fix to any of the routes I've already tried, or let me know if some other avenue is the current recommendation for developing code on this family.Many thanks,James

Hey STI am building an application that has two power sources, one USB-C (27W) with the STUSB4500 controller, and an optional DC input.Because the GPIO or attach pins can be open drain, theoretically they could be used to contrl a second FET on the power path of the DC input. Do you guys think the STUSB4500 could handle this?Also, because the two inputs would be joined, to block revers current, would the STUSB4500 support a back to back FET configuration for the SNK MOSTFET?The power supply's do not need to be uninterruptible, so switching time is not an issue.The two power souses will not be present at the same time.Blue - current path when USB-C cable is plugged in, and sourcing powerRed - current path of DC connector, no USB-C plug present The on board MCU will use I2C to comunicate with the 4500, if the attach pin could be used to switch the power path of the DC input, that should make is so when a usbc cable is plugged in, the DC input is disabledThanksJonas

Hello,What is the pin capacitance for SDA and SCL ? There is no information in the datasheet about this.Best Regard's,

Now the issue concluded to the source of issue. The value of Dtata is 0x38 but its not getting transfered to TFR. Though for other resistors its working fine. The value of TFR always stays 0x00000000.  Since the data is not loaded to Tx FIFO, the communcation not starts.void I2C_FillTxFIFO(I2C_Type* I2Cx, uint8_t Data){ /* Check the parameters */ assert_param(IS_I2C_ALL_PERIPH(I2Cx)); /* Write in the DR register the data to be sent */ I2Cx->TFR = (uint32_t)Data;}

i can't delete this

What is ST system bootloader address. I want to jump the application code to system uart bootloader as the boot pin is not available as of now.Thanks@Winfred LU​  @Eleon BORLINI​ 

Running into lots of problems getting the BLUENRG-M2 to work standalone. When I hook up the expansion board (BNRG2A1), everything works, but not with this chip on my PCB. Verified power and signal wires. Every connection seems fine and I was able to flash the firmware v3.2.0 using the flasher utility via SWD just fine to the BLUENRG-M2.Any thoughts?

I'm using the SPBTLE-1S BlueNRG-1 module on a custom PCB with a STM32L4R9ZI MCU. The SPBTLE-1S module and the main MCU are connected trough SPI. The SPBTLE-1S module can be flashed with various firmwares provided by ST. Which one should i choose? I would like to have it compatible with the code generated by the X-CUBE-BLE1 pack on CubeMX.

Hello, Does anyone know if there is any SPI Flash memory reference source codes available for BlueNRG-2?Our device has additional SPI type NOR flash for file system extension but I couldn’t figure out how to configure it for BlueNRG-2.BlueNRG DK just provides a common SPI source code not for SPI Flash. Thank you.
