Interface and connectivity ICs

I have a NUCLEO-L4R5ZI. I cannot get the virtual com thru STLINK V2 working My PC sees the com port but printf (from other nucleo 144 boards ) does not work. I have tested it with UART3 and LPUART1. Clock is set to Crysta, like for example F767Zi works

BlueNRG-1_2 DK 3.2.1 fails to compile on Linux. The included patch fixes it.

Hi,Compilation of the BlueNRG-1_2 DK 3.2.1 on Linux fails due to two files that were misspelt. The spelling mistakes are due to the fact that Windows file systems are not case sensitive and explains why it compiles on Windows, but not on Linux.For th...

aci_gatt_update_char_value_ext_IDB05A1 causes `HardFault_Handler` to get called .

Hi,When I am using the `aci_gatt_update_char_value_ext_IDB05A1` function with the argument `value_length=118` the board goes to `HardFault_Handler`.I am using Nucleo-H743ZI2 with X-NUCLEO-IDB05A1 BLE Expansion board. The code is here at this specifi...

Hi I am new to the world of wireless modules with ST. I am using the BlueNRGM2SA standalone module without any other expansion boards such as the STVxxx range or the XCUBEBLE board.

I am Trying to figure out how to attach the chip with STM32F411RE. I have looked at the getting started with BLUENRG video https://www.youtube.com/watch?v=BzKIT2T5Q4c. and then have gone to read the programming guidelines in the document PM0257. I h...

BLUENRG-M2SP module programs returns 0x4A on setting the "Blue Flag".

Hi,I'm trying to update the FW of the BLUENRG-M2SP module on my X-NUCLEO-BNRG2A1.I'm using CubeMX with the X-Cube-BLE2.3.1.0 SW pack, together with the IFRStackUpdater application. The IFRStackUpdater works perfectly up to the point where the "Blue F...

Questions re: S2-LP radio configuration and usage, possible bug in s2LP-DEVKIT, and using STEVAL-FKI915V1 as my test boards.

I have written (what I consider) a pretty nice multi-threaded application that configures multiple radios in a network including the ability to forward through intermediate radios. I have most of my system working pretty smoothly.I am more a sw pers...

Hi all I am using Bluenrg m2sp chip as Network co -processor , and its acting as a Peripheral device , and st ble sensor app acts like Central Bluenrg m2sp chip interface with External host Controller using uart with 115200 baud rate .

The problem statement as below.when i trying to read particular characteristic i am getting invalid command from bluenrg2chip to host microcontroller . here i attaching invalid command from chip , how to resolve this , this not occur regularly but it...

I am able to Read however cant write via I2C using STM32F407VGT6 and Proximity Sensor: VCNL36887S

I am able to read the output register 0xf2.And knows this works correctly as I can observe the HEX values change when I hover and remove my finger away from the proximity sensor.However am unsure if I am writing to the registers correctly as they are...

I am trying to communicate with the VCNL36887S via i2c using the STM32F407VGT6 I am able to read the output register 0xf2. However am unsure if I am writing to the registers correctly as they are not impacting the output results as expected.

Please see files attached:Data/application Guide of VCNL36887SImages of function used to read from the output registerand an image of how I am attempting to write.I will also include my code from Keil and CubeMXAny advice would be appreciated Best R...
