Ask questions and find answers on connectivity ICs, focusing on protocols and I2C challenges on STM32 Nucleo boards and BlueNRG products.
Hello everyone,I am developing a custom board with STM32L4 , and looking to include a "ready-to-use" BLE module, such as BlueNRG-2 series. I have in my possession X-NUCLEO-BNRG2A1 and tested it thoroughly. In a previous question ( https://community.s...
Hi everyone,I am new to the ST world and I'm having some doubts about my evaluation.I'm researching for the BlueNRG-LP controllers. As I am sure that the LP series support Ble Mesh so why can't I find the Mesh example for BlueNRG-LP in the STSW_BNRG_...
Would it be possible to have a description of i2c read / i2c write commands (start condition, ack, end condition ... ). I cannot find this description in STSAFE datasheet.best regards,Thierry
I need the BLUENRG-M2SP schematic to qualify the application with the STmicro electronics library. I need to configure the mode of the AC/DC converter. The spec sheet is not documented enough. With the schematics, I will understand what I need.

Hello All,I have recently started using STM32 mcu and quite new to it. I am developing a project in which 3-phase energy meter is needed which measures voltage, current and power of 3-phase AC signal for which MCP3903 IC is used, as I came to know th...
Hi.Chip: ST BlueNRG-345ACPCB: Custom board with VLXSD pin left floating and VFBSD pin ->3.3V, NX2520SA 32MHz, schematic mimics STEVAL-IDB011V1, just bare chip without MEMS or CMSIS_DAP debugger, just MCU, decoupling capacitors, chip-antenna with matc...
Hello, I'm a student engineer and I'm working on a project which aim is to retrieve environmental data such as Temperature, Humidity and luminosity... and to send them via Bluetooth to my phone. I'm using STM32F401RE board + X- NUCLEO- IDB05A1 and co...
