Interface and connectivity ICs

When my Raspberry Pi with BLUEST-SDK-PYTHON is connecting to the STWINKT, my Android Phone with ST BLE Sensor app cannot connect to it and When my Android Phone is connect to STWINKT, my Raspberry PI cannot discover or connect into it (I am using exampe_ble_1.py)

Using the google cloud platform, have connected via the STLINK, have configured the modem using the binary file provided for google cloud platform. Using an NBIOT external sim card but when the APN is set for C2C capability, the response on the terminal is:Initializing the C2C moduleTrying to connect with the external SIMC2C AT communication error with the C2C deviceC2C device might be disconnected or wrongly connectedTrying to connect with the embedded SIMC2C AT communication error with the C2C deviceC2C device might be disconnected or wrongly connectedError initializing the module!Firstly, i dont want to use the embedded sim, only the sim card i have inserted. Previously using AT commands i always able to set the APN and atatch to the network, however in this configuration it is not working. Any thoughts as to what I could do to make sure my C2C device will work/connect?Thanks!Jason

Using an Aukey PA-Y10 supply with the STUSB4500 works fine for all the five fixed-voltage PDOs (5V, 9V, 12V, 15V and 20V).However, the supply's manual says that it features a PPS output with 3 to 16V but I found no way to access this with the STUSB4500. The source-capabilities message just lists the five fixed-voltage PDOs.So how can I access the PPS (programmable power supply)?

I use SDK_Chat example (S2LP DK1.2.1\..\S2LPLibrary_Examples) as a base for my project.To increase a Communication range I change next parameters:DATARATE                   38400 (default) to 4800POWER_DBM                  12 (default) to 14RSSI Threshold SRssiInit *x->cRssiThreshdBm -106 to -130Question: Are there another parameters, which may be changed in SDK_Chat example to increase the Communication range?

I am using an M41T62 to test the various repeat modes using bits RPT1-RPT5. Most of the repeat modes appear to be triggering an alarm properly, with the exception of MONTH (only RPT5 set) and YEAR (RPT1-RPT5 clear).For example, to test this, I set the time to Tues, 31 Dec 2019, 23:59:45 and configure for either MONTH or YEAR repeat mode. The date rolls over as to Wed, 1 Jan 2020 but I do not receive and IRQ and AF is not set. I have also tried, for example, setting the date to Tues, 1 Oct 2019, 23:59:45 in case the MONTH repeat mode triggers at the end of the first day of the month.Is there something I am missing?

Hi all,I recovered 2 old ST7540 DEMOKITs complete of the related ST7-based COMMBOARDs (photo attached); however I don't have the DEMOKIT GUI that is cited in the UM0239 I found on the ST website (https://www.st.com/en/interfaces-and-transceivers/st7540.html#resource).As it seems this software is not available for download on the ST website; is there anyone that has it?Thanks in advance for any answer.

The LEDs labeled Sensor 1, Sensor 2, Sensor 3, and Sensor 4 are all flashing on my board even though I have the STEVAL-IDP005V1 connected to an IO link port.Are the lights supposed to keep blinking when I connect a sensor or do the blinking lights mean there is something wrong? They don't stop when I disconnect the sensor.

Hi,I'm designing a beacon around the BlueNRG-2 and would like to power it from a battery that can output as much as 3.67V. Unfortunately this exceeds the max Vin limit on the datasheet (3.6V) by only 70mV. I have a couple of questions in the hopes of reducing complexity and improving efficiency.I've heard some MFGs relax the limits on a part over time, is there any chance that this may be the case with the BlueNRG-2? If so, what is the most up to date limit? Is there any concern about regulating the battery to the limit of Vin, i.e. 3.6V? Are there some conditions in which this could be problematic?Thanks!jay

Is there any plastic box for  STEVAL-BCN002V1B board. And what is maximum data size which we can sent via bluenrg-2 when BLE characteristic is configured as notify?Thank you in advance, Nikola

I am using NRG-1 for my product development but I have only NRG-2 kit on hand. I am using NRG-2 project to develop my SW for using DK kit but I found there are 250kHz frequency offset when the software is applied to my HW for using NRG-1 inside. Is there any setting to be difference in NRG-1 and NRG-2 in latest 3.1.0 SDK apart from the high clock setting from 16M to 32M?

Hi all,I am working on NRG-132 for my product development and it is fine for spectrum with Power Level from 0 - 14 (ie -18dBm -- 4dBm). However, when I set to powerlevel = 15 or PA_level in BlueNRG GUI in level 7, the output spectrum will be distorted and large spurious is around.Any suggestion in hardware problem for such problem?

I am looking for troubleshooting suggestions for a BLUENRG-MS with a STM32 processor. There are cases where calls to aci_gatt_update_char_value() return 0 but the client subscribed for notifications isn't receiving any. There are other code paths where this is working and I am looking for suggestions of things to examine.

I'm using BlueNRG132 (QFN32) in a custom PCB project. Currently I'm using BALF-NRG-01D3 chip, but I would like to know if there are other options of Balun Chips to use with BlueNRG and 2.4 Ghz (50 Ohm matched) antenna. On the other hand, I would like to know how you use to build your balun circuits with BlueNRG; chip or discrete components?Thanks in advance!

Hi, i am new to using ST boards. I am using a broadcaster which only sends data after every particular interval. I want to use resolvable and non resolvable private address techniques to secure the data sent and direct it only a particular user and not accessed by other. Can I please know how to implement it in Keil. I am having trouble in programming it. And if there are any suggestions on other better ideas to secure please let me know. I am open to new ideas.Thank you.

iam trying to implement ble ota service in bluenrg tile .is it possible to firmware ota update usingble app?if it is possible what are the procedure to activate ble ota application in sensor demo application ?

We are IC programmer manufacturer, and we will help customer to develop this part on programming handler. Please let us know if we need to sign NDA.

More spesicifly , I could not calculate the data size for every image and I am not able to determine which wireless communication protocol for mobile phone suits to my project. Would you guys give me clue,reference or idea?

Dear all,I have 2 NUCLEO-L476RG with 2 I-NUCLEO-LRWAN1 lora shield.I plug the shield on the nucleo, connect the antenna, connect the nucleo on my computer, and I compile and load the ping_pong demo program sx1272mb2das from "en.i-cube_lrwan" into each nucleo board.Then, i open 2 terminal com, with 115200 bauds, 8bits, parity none, 1 stop bit to see the ping pong message, but I only have TxTimeout and RxTimeout on each nucleo.Can you help me to understand the problem ?Thanks in advance.Best regards,Jerome

Hello,I want to know about how to calculate max attribute records when I want to add server ? Is there a limitation of number of servers or characteristics ? If there is a limitation about characteristics or servers number, how many byte or number?Thank you for reply.Asımwww.rmftek.com

Please let me know the SpiRaw function data format in S2LP-SFX-DK. in_buffer [0] - 0x00 is SPI Write, 0x01 is SPI READ, 0x80 is Command in_buffer[1] - SPI Reigster Address or Command in_buffer[2]~ - Write Data

HiI tried to develop my own code for s2lp on NUCLEO-L476RG my setup include:NUCLEO-L476RG+s2lp FKI433v2 on top(RX working fine)NUCLEO-L476RG+s2lp FKI433v2 on top(TX cant go to TX mode)NUCLEO-L053R8+s2lp FKI433v2 on top(as a test for both RX and TX)I was able to receive messages with the my code on the RX side the message was from the L053R to my L47RGHowever when I Tried to send From TX L476RG it Wouldn't send Nor Got to TX modeI know this because i saw the S2lp status Bit after I sent the TX Command it didn't go to TX MODE but Went to Ready onlyThe status Bits were(52  1) I am using kiel V5 and did initialize with Cube MXvoid FLUSH_FIFO(){ UARTBuf[21]=COMMAND_FLUSHRXFIFO ;   HAL_SPI_Transmit(&hspi1 , &UARTBuf[20],2,500); HAL_GPIO_WritePin(SDA_GPIO_Port, SDA_Pin, GPIO_PIN_SET); HAL_Delay(50); HAL_GPIO_WritePin(GPIOA, GPIO_PIN_1, GPIO_PIN_RESET); UARTBuf[20]=0x80; UARTBuf[21]=COMMAND_FLUSHTXFIFO ; HAL_SPI_Transmit(&hspi1 , &UARTBuf
