Ask questions and find answers on connectivity ICs, focusing on protocols and I2C challenges on STM32 Nucleo boards and BlueNRG products.
Hi,I am trying to use subGHz RF modules in my design. I have following questions. It would great if any one could answer these questions. I am trying to build sensor nodes + Gateway. Planning to use mesh over sub GHz.What is the difference between S2...
Hello,I created a BLE peripheral using a BlueNRG-MS chip. I can connect on this peripheral using a BlueNRG-M2 (using BlueNRG GUI) and read the services.However, it does not work when I try to connect with an android device (I use "BLE Scanner" app, B...
Hey all, We received our evaluation kit in the mail today and I'm trying to get some "Hello World" projects running. I'm using IAR 8.50.4 and have had success flashing the example projects to the board using the Navigator and by dropping Hex files in...
Hello, can you help me recognize the S2LP version. I read the register DEVICE_INFO1 and I get 0x91 on the RC-S2LP-433 and in the Steval-fki433v2 is 0xC1. I have some problems with RC-S2LP and I think there is a different version of ic. Thx.
Good Morning everyone, lets brainstorm.Against my will, i might be designing star topology CANBUS networks.So i need to figure out how to set in firmware the EOL resistor value. My ideas:Rele activated EOLs, expensive and bulky.Programmable resistor ...
Starting from ST EVMboard "B-L072Z-LRWAN1" I made my PCB with the murata module "CMWX1ZZABZ-091" (LoRa/Sigfox). To put my board to work, I have done the "id request procedure" with success, the same as I did for EVMboard.Now I am plannig to go in pre...
How can I do such kind of interfacing. Also note , this TETRA device needs a specific USB driver to install and run while connecting with the PC windows. Does the development board can support only those usb devices which don't need a driver run?
Do you have a typical schematic or an application note that deals with such a setup, to have direct hardware control of the TX- and RX-mode, and also to access the TX and RX data in a very direct way?In our application the TX/RX time and RX/TX time i...
Hello. I have STEVAL-IDB008V2 and I have 1 service with 5 characteristics for BLE. I use SensorDemo program coming with STSW-BLUENRG1-DK for tests. Problem is that I can not add more services and characteristics because Out of Memory error is receive...
