Can not connect STM32WB55CGU6 with ST link
I'm using STM32WB55CGU6 (UFQFPN-48) for a design and trying to connect with the ST link. But seems like it is not connecting in any way. Can anyone tell me how can I connect this MCU and upload the firmware to this MCU? Why it is not responding?
STM32WLE5JCI6 all bands activation
We are probably need a support from the ST team with the implementation of the LORA (STM32WLE5JCI6) supporting all four frequency ranges.ST has provided two reference designs, one for LB, one for HB. We have combined them together and made it not on ...
Resolved! Spurious BLE disconnection
Hi,I am using two device that are connected one to another with BLE.The first device is a server.The second is a routeur.I detect some spurious disconnection between both device after some random time.The disconnection error I get is : HCI_CONNECTION...
What is the maximum value of HS_STARTUP_TIME for BlueNRG-1?
Hi friend,I want to extend the HS_STARTUP_TIME for BlueNRG-1. What is the maximum value of HS_STARTUP_TIME for BlueNRG-1? I saw the datasheet AN4494 it says that "XTAL_startup = XTAL_startup_measured*1.2*1.1*1.3 = 1.716*XTAL_startup_measured". So 19...

Resolved! STM32WB10CC RF output stage design question
Hello, For a personal project, I am designing a device that receives GPS data and transmits the UTC time information to other devices over BLE. I will also be designing a device that receives the data and displays it. For this, I have chosen the STM3...
STM32WB55 Trace Configuration Issue - No Trace Data
I've been working with the STM32WB55 microcontroller and have been trying to set up 4 bit trace functionality (ETM, not SWO) for debugging. I've connected the trace pins according to the datasheet and configured them in the STM32Cube software.Specifi...
Cascading LPTIM in STM32WL55JC17
I'd like to know if it is possible to cascade two LPTIM in order to make a 32-bit counter. I'm implementing my main LoRa application with the sequencer but I need to have 32-bit hardware counter running continously in the background to count external...
Can't get ADC to work in HeartRate example on STM32WB15 when CFG_LPM_SUPPORTED is set to 1.
I've modified basic HeartRate project to run an ADC inside of the task. However this results in adc always returning 0. Sometimes whole application hangs. However when CFG_LPM_SUPPORTED is set to 0. Everything works fine. I've already created github...
Resolved! BLE Advertising Problem
Hello,I am working on a STM32WB55RG BLE Project and the problem is that about once in every 3 program that I upload, BLE doesn't work. After reupdating the BLE Stack firmware, it works correctly. I am using the BLE firmware v1.16.0.4. What could be ...
