Interface and connectivity ICs

I have tried putting the device_id[4], PAC[8], Offset[4], Private_key[16]. Where can I find information on this ? Thank you

Good day!The question is:What temperature and for how long time I can heat BLUENRG-132 after programming without breaking the data ? In the experiment, data is saved after soldering. But, I want to understand where this is written in the documentation, to be sure. Maybe soldering profile can be interpreted as safe heating for flash data ?This question concerns all processors, since appears periodically.Thank in advance !

Hello,we have developed some custom boards with S2-LP transceiver and BALF-SPI2-01D3 balun coupled. We notice a non-linear behaviour between the output power set to s2-LP and the measured output. By direct connection between signal analyzer and S2-LP, we measured that from 0 dBm to 14 dBm with 1 dB step, we have measured a constant step of 1dB with 10% tolerance.When the balun is connected, we notice that the power step is quite similar in the range from 1 to 10 dBm ( about 1 dB), while from 11 dBm to 14 dBm we notice a significant increase from 1.2 dB to almost 2 dB measured instead of 1 dB set. We notice this on 3 different board layout. What can be the cause of this step increase when the balun is present in the circuit?

Hi We are using BlueNRG-MS IC for BLE communication, in that we are facing issue with Balun filter IC package. BALF-NRG-01D3 /02D3 having  CSPBGA package which we are unable to solder, so we are looking for alternate package or any alternate method for balun filter.Please help in the above issue

Dear all, I am new to STEVAL-BCN002V1.I will like to inquire if there is any workshop presentation materials or materials which can explain to me the code walk-through for the entire STEVAL-BCN002V1.As I will only use acclerometer and pressure sensor to get free-fall function, step counter, acitivites recongition.Also, I will like to ask why am I able to add the customised C code which I had build using algobuilder to the whole project.Please teach.Best RegardsGary

Hi I want to develop OTA feature for SPBTLE-1S. For this I am referring projects of bluenrg-1 development kit, but I am facing so many issues in libraries. If any one can help me in this issue will be great full

Hi everyone,I am trying to set up CSMA/CA on the S2-LP.Depending on the rssi threshold (RSSI_TH) it may be functional or not.If I set RSSI_TH very low, data packages are not transmited and I get the interrupt "Max.number of back-off during CCA". As expected.However, if I set RSSI_TH higher the S2-LP stays in RX state. Even though carrier sense is 0 it just does not send the package. Sometimes after waiting for minutes I get the interrupt "Valid preamble detected", and afterwards the package is transmitted, followed by interrupt "TX data sent".Why does the S2-LP send the package only after receiving a valid preamble? CSMA should send the package immediately if the channel is free i.e. carrier sense=0, right?Thanks for any hints and help.

Please share any basic code of LED ON/OFF for Arduino mega adk.

Hi do i need an external txco for narrowband operation?regards

Hi everyone,I'm trying to pair an Ubuntu machine with SensorTile using Bluez, in the tutorial n. 6 it establish a pairing with a Beaglebone without any passkey requested, while in my case Bluez require me to enter the passkey, but I can't find it anywhere and I've already tried 0000, 9999, 1234, 123456

Hello,While reviewing the provided Android app, I couldn't find any source code for the SensorModelClient class. Is this available anywhere? I'm trying to understand where the ongetSensorStatus handler is called, and the javadocs don't have enough information.Thanks

I have an nRF52 DK and a CR95HF development board from Mikroe (https://www.mikroe.com/rfid-click) and I'm using the Nordic SPI SDK version 14.2.0I have managed to get the device to communicate with the CR95HF and got through the calibration phase, where at each step it correctly responds to the requests.I am developing on Linux.However, after sending REQA, to which it responds correctly for my MIFARE Classic card that I'm using as a test device.I then have to send Anti-Collison, to which it doesn't respond and only after sending many of these same requests repeatedly do I get an 0x81 response.The only other response I've gotten is 0x82 which is "invalid protocol" per CR95HF documentation. The reqa request and anti-collision look as follows:/* REQA from tag */   uint8_t m_txreqa_buf[5] = { 0x00, 0x04, 0x02, 0x26, 0x07 }; uint8_t m_rxreqa_buf[11] = { 0x00 };   /* Anti-collision */   uint8_t m_txantcl_buf[6] = { 0x00, 0x04, 0x03, 0x93, 0x20, 0x08 }; uint8_t m_rxan

Hello,I want to add a BlueNRG in my design and I would like to use the TCXO used on the processor (STM32L451) and connect it on FXTAL, is possible possible ? if yes on which pin ? FXTAL0 or FXTAL 1 ?I would like to do the same thing with the 32.768KHz, and use the LSCO from the STM32 to the blueNRG, is possible possible ? if yes on which pin ? SXTAL0 or SXTAL 1 ?regards,Benjamin

Hello everybody, i need your help. To store data on my STM32, I need about 4-8GB storage.What kind of memory would you choose and why? I was thinking about eMMC but I have not found a development board or test board for a eMMC BGA. Do you have any other suggestions?Thanks for your help.

The current documentation focuses on only STM-32 using the platform STMCubeMX studio. Any generic datasheets or Code samples will help.

I am newbie of ST controller.I am working with STEVAL-BLUEMIC-1. this module contains spbtle-1s which is based on BlueNRG-1. According to the application note AN4869, firmware can update using another BlueNRG-1as central.But I want to update firmware using mobile app. Is it possible and how?

I am about to integrate the BLE module SPBTLE-RF which is Bluetooth v4.1. My PCB already have the footprint of the module, I just need to integrate the firmware. But I heard the Bluetooth Special Interest Group (SIG) recently announced the deprecation and withdrawal of Bluetooth Core specifications v4.0 and v4.1.What does it mean to my case ? Is it worthy to keep developping this module or do I need to make antoher PCB version and choose a BLE module v4.2 minimum ?Thank youGael

Hi, I am Omar from Egypt. I got recently a ( STEVAL-IDB001V1 ) Kit which based on STM32L152 Discovery board.Unfortunately I didn't find any source code for the STBLC01 Bluetooth 4.0 low energy and I only found a 40 pages datasheet which doesn't has more technical data about making a code for it. Could you help me with any data ?Also if you have any code examples or any information about the ( STEVAL-IDB001V1 ) kit it well be appreciated. Thanks a lot.

As SPBTLE-RF module is already CE certified and I have its test reports also. But as a complete product we have to perform this tests again: -1) As per EMC EN 301 489-1 V1.9.2 / EN 301 489-17 standard: - a) Radiated Emission b) Electrostatic Discharge 2) As per RED EN 300 328 V2.1.1 standard: - a) Transmitter unwanted emissions in the spurious domain b) Receiver spurious emissions.By the test report it is not clear that how EUT means SPBTLE-RF module is configure while this above test performed.Our queries are: -1) Can any one share me How this module is tested during above tests. Testing method we will follow as per standards but how module is tested or configured or communicating with other device while above test are perform?2) How Radiated Emission test performed ? As in certificate snapshot it is not cleared.3) How Transmitter Spurious test and Receiver spurious test performed? In which only BLE will either continuously transmit or receive signal at maximum output power.4) Is

Hi,I know that RF transceiver is affected by obstacle.What's the scope of S2-LP RF transceiver with/without obstacle?Is there an analysis on S2-LP RF transceiver?Best Regards,Mohamed Amine.

Hello there,I am working on Smart Home project using BLE technology. The system needs to have a BLE mesh network to control smart switches. I wanted to use STM32F030R8 connected with SPBTLE-RF BLE chip for BLE mesh network. When I searched for the same, I found cube package X-CUBE-BLEMESH1 which includes BLE mesh code ported for some ST microcontroller series like L1, F4 etc. I have tried to add package in STM32CubeMX v5.2.0 using "From Local" option but, it says the Cube version doesn't support this package.I want to generate or port the BLE MESH code for STM32F030R8.Please help me to generate a code (for IDE SW4STM32) which supports BLE MESH on STM32F030R8 connected with STBTLE-RF.Thanks in advance.

After once BLE Initialize and authentication set by fixed pairing key as "123456" then can we change again pairing key to "123678" by using this API "Aci_Gap_Set_Auth_Requirement()".Means BLE will disconnected and I will configure its authentication fixed pairing key with other value during run time of my application. To ensure security as fixed pairing "123456" can known by unknown user also and he will connect to device easily but if I will change pairing key to some other value (whatever user wants of 6 digit) then unknown user will not easily connect to device which will secure my device.
