Ask questions and find answers on connectivity ICs, focusing on protocols and I2C challenges on STM32 Nucleo boards and BlueNRG products.
My customer installed some sites with cards with S2-LP (one central board and one remote).On a particular location the S2-LP crashes. Now I'm searching the problem but while I'm searching I would like that the customer resets the S2-LP (not the entir...
Hi,I have a custom PCB based on STM32L4R9 with a SPI interface to BlueNRG-2 flashed with DTM SPI (2.1f stack). I use X-CUBE-BLE2.I'm able to communicate with the module such as retrieve firmware details, start and stop tones. The problem I'm seeing i...
Using WiSE-STUDIO and BlueNRG SDK 1.4.0 on Windows 11Debugger is USB to the board, configured as CMSIS-DAPI'm able to flash code to the board, but I cannot see an option for "Live Expressions" anywhere. Is this not supported?
Hi,I notice that the STHV series chips have T/R switch in it, but I wonder if the evaluation board can receive the echo signals? Then, if I want to develop a PCB board with STHV series chips, do I need to add a waveform generator before STHV chips?...
Hello,I'm from Viet Nam,I am currently working on a project to use eSIMs for electronic meters.Can you show me how to bootstrap VNPT's profile to your eSIM chip? (VNPT is a major telecommunications corporation in Vietnam)Best Regard!
Hi everyone,I am developing an IOT solution using the BLUENRG-M0 from ST.I am coding in C and I use a custom board with SPI communication between the BLUENRG and my MSP430F5255 from T.I . I am using the ACI API to transmit commands to the BLE module....
My prefered distributors are :Mouser, Farnell, Digikey, RadioSpares
Hi,We are using Murata CMWX1ZZABZ-078 Lora module and I-CUBE-LRWAN firmware for our IOT project development. There is another host ( STM32) MCU sending AT command at 115200 baud rate to control murata lora module and it works fine at room temperature...
