Achieving Lowest Power Mode with a persistent BLE Connection

I am working on a project where we would like a responsive and secure BLE connection to a battery powered sensor. If a supervisory timeout of 32 seconds is set, would the STM32WB be able to go into Standby while no data is needed to be sent and still...

Downgrading BLE firmware

I have a WB55 with FUS 1.2.0 and I'm trying to use zephyr. However, zephyr is only tested up to v1.5 of the BLE firmware. I've tried everything from 1.5 to 1.13 and the lowest version I'm able to flash is 1.11. Is there a method to get to an older fi...

Unable to connect with LE privacy on and advertising for 15 minutes?

Ok, I set up a random static address and I also enabled LE privacy with GAP init. Everything seems to work fine unless I let the device advertise for 15 minutes (with a random resolvable address). After 15 minutes, I can still see the advertisement...

STM32WB Application recieves hardfault keyword after TL_Enable() is called

In a project with STM32WB55RG + FreeRTOS, calling TL_Enable() often results in a Hardfault with the keyword @SRAM2A_BASE: 0x1170FD0F (picture).Hardfault is repeated regularly until you make a small change in the code in any part of the program. After...

Is there a document on how to set up Bluetooth on the STM32WB series boards?

I have been trying to do a bunch of research on the various Bluetooth documents around the forums and STM's site. I seem to see that the ACI api's are a higher abstraction level than the BLE stack but I do not know how to use them. If anyone has docu...

I-CUBE-LRWAN flash optimization

Hi,I need more 4kB of flash memory. Can I achieve this easily and safely by removing some not used functionality in the I-CUBE-LRWAN project?I suppose Lorawan Class B and C featues will not be needed. Can I just exclude this files from the project an...

Resolved! STM32WB Fails on SHCI_C2_BLE_Init

Hello! I'm working with a custom STM32WB10CCU board and can't seem to get BLE working.Here are the details:I have no LSE on the board.. just HSE. I'm configuring RFWKP to HSE/1024 and RTC to HSE/32 (I know that LSE is strongly recommended -.. but fro...

Recommended TCXO for STM32WL Design

We design a new product where we use STM32WL microcontroller and in the datasheet ST is recommended to use NT2016SF-32M-END5875A, it was not in stock everywhere. We planned to use the ECS-TXO-20CSMV-320-EY-TR TCXO in our design. Please share your rec...
