Good Afternoon,I am new to the community and I have a missunderstanding about a functionnality .I have seen that to put the BNRG-2 in sleep mode it is necessary to use the function : BlueNRG_SleepMy probleme is that I use an evaluation kit and I don'...
Hello,I am implementing a BlE client (central) to display the information being transmitted for a couple of ST SM32L4 boards.So far, I am getting the information on my application but I don't have a way to determine what sensor that data corresponds ...
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?
