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...
