Interface and connectivity ICs

I would like to implement MQTT protocol over LAN using ETHERNET Peripheral in STM32 microcontroller. Please let me know any resources for this. And is it necessary to use RTOS for implementing ETHERNET protocol?

Help with ST BLE Sensor sample application, with STM32F103RB and X-NUCLEO-BNRG2A1.

I am a student, and am using ST BLE Sensor app with STM32F103RB and X-NUCLEO-BNRG2A1. I am looking to adapt the sample application to use as a demonstration in class, but I can't seem to find where, in the code, the Nucleo board takes input from the ...

BLUENRG-LP Antenna Matching Guide

I am developing a new product using BLUENRG-355AC and need some help regarding the antenna matching circuit. I am planning to use an external 2.4GHz antenna connected to a SMA connector on the board. The BLUENRG-LP series has two evaluation boards ST...

How do I read the unique serial number of the ST BlueNRG-LP(BlueNRG-345) device that I need to use as the default MAC address

Q1: For the modules BlueNRG-M2S(P) and (A): What ist he sum of capacitors (µF) and inductances (µH) in each module (is required for ATEX certification)? Q2: Are these modules washable after assembly on the PCB, for subsequently coating/potting ?

Hello,for one of our customers in the sector of process automation, we are evaluating different BLE modules including your BlueNRG-M2SP and BlueNRG-M2SAFor our evaluation, there are two requirements we must know, to verify their capability to be cert...

i cant read and send data between UART2 of a STM32L476rc (PA2 and PA3) and the BlueNRG-2N UART(DIO8 and DIO11), i want to read the hw and fw version of the blueNRG .

I designed a PCB with an STM32L476rc and a BlueNRG-2N, the buenrg is conected with usart3 and i want to read the bluenrg version and send it to usart2 to show it with docklight please can someone give me a hand in the source code ,

BLE performance of BlueNRG-2N

Hello everyone, I am designing a custom board (STM32L476 MCU paired with BLE connectivity, among other components) and after search decided to use BlueNRG-2N module along with Antenova A5839 Antenna.Tried to follow AN4819, despite the tight PCB space...

What are the effects of clock drift in a multi-master setup?

I have three devices. D1 is Master of D2 and Slave of D3. D1 is Master and Slave at the same time. D1 must receive a packet from D3 at the anchor point, and must send a packet to D2 at another anchor point. Because of clock drift, I would expect thes...

S2-LP star topology examples

Hi,I am successfully using S2LP with contiki NG. Works great. I have requirement of using S2-LP in star topology. Does ST provides any examples or Eval software or kits? I tried searching but no help. Any help around this is appreciable.Thanks,Naveen
