"no device detected" in BlueNRG GUI, using X-NUCLEO-BNRG2A1
Hi, I use a X-NUCLEO-BNRG2A1 with a NUCLEO-L476RG .I try to use the BlueNRG GUI for the Virtual_COM_Port application. I copy directly the binary file into the "NUCLEO" device. But when I open the Port on GUI, it is displayed "no device detected" then...
Clock division and duty cycle for ST8034P
In the Data Sheet for the ST8034P the following is not clear about the ST8034PQRwhen the CLK output is active, does fCLK = fCLKIN or fCLK = fCLKIN/2 ?assuming fCLK = fCLKIN: is there some duty cycle (or other characteristic) to be met on the CLKIN in...
Resolved! BLUENRG-LP Embedded UART Bootloader Crash Errata
Hello,We are in process of selecting a suitable BLE SoC for an industrial sensor network design which would support coded PHY LR communication. The BLUENRG-355Ax MCU fits all the requirements perfectly except for one major point - Embedded Bootloader...
S2-LP: No length byte in RX packet... finish RX on RSSI level?
Hi there,I am trying to use the S2-LP as a packet sniffer to receive proprietary RF packets that do not contain a length byte. Is it possible to configure the S2-LP to finish RX by monitoring the RSSI level? How?Thanks in advance,Pieter
Skipped codes in BlueNRG-LP ADC
Hi,I'm seeing some very strange behavior on the ADC of the BlueNRG-LP. It looks like the ADC is skipping codes near the inversion point of a differential input, with similar behavior in single ended mode near 0.9V (with a 1.2V reference). This is on ...
BlueNRG-MS always returns a 0 bytes available on tx buffer
In a custom board using BlueNRG, sometimes, specially while using external debug interface, we fall in a condition in which BlueNRG get "broken". Investigating more in deep, we discovered that sending the write "header" packet (0x0A, 0x00, 0x00, 0x00...
BlueNRG2 - RPA cannot be resolved inside controller (LL_ONLY)
Hi,we are issuing some problems regarding BNRG2A1 used in LL_ONLY mode (we are using an external bluetooth stack running on the host).This is our setup:X-NUCLEO-BNRG2A1 mounted on NUCLEO-STM32L476RG. The BNRG2A1 firmware is the DTM_basic SPI example ...
PSI5 ECU to sensor Communication via L9663
ST‘s engineer: Hi. PSI5 ECU to sensor Communication like this: But I cannot generate this waveform via L9663 ——no matter how I configure the registers. How to configure L9663 registers to generate this waveform via spi or pin?Thanks!
How to read IO-link sensor data with P-NUCLEO-IOM01M1 master?
Hello,I am using a P-NUCLEO-IOM01M1 kit that is made out of the STEVAL-IOM001V1 evaluation board and the NUCLEO-F446RE microcontroller.I would like to read an IO-Link flow sensor made by Keyence(FD-H).In order to achieve this I want to use the STSW-I...
