AT_RX_TIMEOUT from downlink request using AT modem commands (ST The B-L072Z-LRWAN1 LoRa®/Sigfox™ Discovery kit )

I am using the CMWX1ZZABZ in the ST The B-L072Z-LRWAN1 LoRa®/Sigfox™ Discovery kit with STM32CubeExpansion_SFOX_V1.1.0. The application being used is the Sgfx_ModemAT. I have successfully sent data to our Sigfox backend, I also see from the backend t...

BlueNRG-355VC MCU, GPIOs as inputs, interrupts on logic level changes

Hi.I'm going to use in a design the SiP below, which contains a BlueNRG-355VC MCU inside.I have found the datasheet titled "BlueNRG-LP", and I was reading about the features of the GPIOs.When used as inputs, they can have internally connected pull-do...

X-CUBE-BLE1 BlueNRG-MS: MX_BlueNRG_MS_Init() and MX_BlueNRG_MS_Process() Not in Generated Functions Call

Hello,I am trying to make my first Bluetooth firmware to do a very simple function (Use Bluetooth app to turn an LED ON/OFF). My versions for everything is as follows:STM32CubeMX: 6.6.1X-CUBE-BLE1: 6.2.3My components are:NUCLEO-F401RENUCLEO-IDB05A2I ...

Alternative of X-CUBE-BLE2 for BLUENRG-LP series

Hi, CubeMX offers two software packs for BLE boards using BlueNRG chips as Bluetooth modules/slaves, one pack for BlueNRG-M and one for BlueNRG-2.However, I could not find one pack for BlueNRF-LP. There is, however, a module called X-CUBE-BLEMGR, but...

RE-programming SPBTLE-1S from beacon mode to BLE

I bought from gilisymo a ToF sensor with integrated BLE based on SPBTLE-1S from ST. Right now the BLE is setted in beacon mode to save energy but i would like to pass to std BLE communication in a way to acquire the signal at fixed frequency. Unfortu...

Where should the EP (Exposed PAD) for the L9825 (Part Number) driver IC be connected?

There is no connection diagram for EP in the datasheet. We are using an LDO (Part Number: LT1121ACS8-5#PBF) to convert the supply voltage for the L9825 (+24V to +5V), and we are providing the L9825 with +5V as a power supply. LDOs have a common groun...

RSSI value not changing in BLE Mesh Network?

Hello ST,@EMECH​ ​I am using BLE_MeshLightingProvisiner sample project. We try to trace the RSSI value from the below mentioned function:: BLEMesh_NeighborRefreshedCallback(const MOBLEUINT8* bdAddr,                     MOBLEBOOL provisioned,         ...

How are the D+/D- lines connected when implementing the STUSB4500 for power purposes? In this case we want a Pi4 to act as a device, but power is handled separately.

STUSB4761 - I2C Device address missing in datasheet

Relating to STUSB4700 / 4710 datasheet I suggest the device address is the same as for 4700 with all adr pins set to 0.But no description in 4761 datasheet for I2C interface or register map.

How to emulate BlueNRG-2n with BlueNRG-2

Hi,We have a custom board with BlueNRG-2 and wants it to act as a co-processor so it can be controlled through SPI from another MCU (STM32L4R9).The BlueNRG-2 has been flashed with STSW-BNRG2N-V320 firmware through the bootloader interface.DIO0 SCKDIO...
