Ask questions and find answers on connectivity ICs, focusing on protocols and I2C challenges on STM32 Nucleo boards and BlueNRG products.
I’m not RF expert and I know that my question is very very general.I have to communicate with RF S2LP device using a not ST microcontroller, but at the moment my firmware can read and write the S2LP registers by SPI. It works correctly.The RF CC1101 ...
Am searching for Automotive Compatible BLE SoC from ST.I found BLUE NRG series.Is BLUE nRG 2 Automotive Compatible? Please help me with this.i am asking this because only this one meets my temperature criteria.
Hello, I have ST EVB for the chip STuW81300 - wideband synthesizer chip. To control this EVB I use software STSW-RFSOL003. Unfortunately not all chip settings are available in the GUI, e.g. "CP lekage current" or "Down-split current" in the register ...
I have followed this tutorial: https://www.youtube.com/watch?v=eiknW5Ml9dA and also downloaded the code from here: https://my.st.com/content/my_st_com/en/products/embedded-software/mcu-mpu-embedded-software/stm32-embedded-software/stm32cube-expansion...
Dear Team,We are designing a project where the supply is battery driven. We would like to go with USB Power Delivery(PD) for fast charging and high power management. Basically we are using 3S Lithium 18650 battery(3 batteries in series = 11.1 V), whe...
I am using this ST-LINK/V2 for programming bluetooth chip BGM11S through SWD.This bluetooth chip has SWD-pins for communication.But ST-LINK/V2 can not connect with this bluetooth chip, there is an error: "Unknown or unsupported device (DevID = 0x0000...
is there anyway to handle/ call when the device unexpectedly disconnection so that when the unexpected disconnection happened it could do software reset by itself?
Hello, I'm looking for a nucleo board with the module BLUENRG-M0L or BLUENRG-M0A.Is it planned to develop a such board ?Regards, Dam
I am experiencing a problem in bluenrg-2/bluenrg-ms where after the STWINKT wakes up from standby mode, I am able to advertise the STWINKT but after the other device connects to the STWINKT and receive some of the initial data, it freezes up and then...
The BlueNRG-2 has multiple communication protocols available (UART, SPI, I2C). I am planning to use it in a custom PCB and would like to configure it for SPI, which I can only find mentioned in Section 3.8.2.2 "Procedure for enabling SPI" in the Blue...
