STM32 MCUs Wireless

Clear Difference between DFSDM and SAI

In our previous design we were using DFSDM to read the microphone data, but with the STM32WB family there is only SAI PDM port. I read that the SAI consume more power than the DFSDM because it is processing PDM to PCM. I found also that the DFSDM is ...

Anyone know how to set the WB55 for limited discovery from within the Cube?

I notice that there is an API, aci_gap_set_limited_discoverable(), which is designed to time out the STM32WB55 if no connection is made within a certain period. However, this option does not show up within the Cube (v6.2, just released) when setting ...

FUS_STATE_ERR_UNKNOWN when programming wireless coprocessor over ST-Link on STM32WB55

I am attempting to load an image onto the wireless coprocessor of the STM32WB55CGU6. I am using STM32CubeProgrammer through its wireless image tab to accomplish this, and I am following the instructions in the release notes provided with the binary i...

STM32CubeWL LoRaWAN ATSlave and endpoint example assistance

Hi, I've been trying to figure out how to get the above-mentioned LoRaWAN examples working on a STM32WL5 devkit.I'm at the point where I can join with OTAA on a Multitech gateway on the Things network, but I can't seem to get the devkit to then send ...

High current consumption in standby mode after starting CPU 2

Hi!My project consists of a bootloader and a main program that uses BLE functionality. If, after turning on the device, the main program was not started, then after switching the bootloader to STANDBY, I get a current consumption of 5 µA, taking into...

STM32WB55xx reference manual, section 3.7.2 specifies startup on MCU - first 1.8V and then 3.6V for USB, (Vusb must be started when Vdd is at least 1V). If I fail to follow it, what happens ?

Its easy to fulfill requirements for startup ( I turn 3.6V LDO enable with 1.8V voltage), but when powerdown, the 3.6V decay is much longer and if 1.8V is already decayed, there is still 2V on 3.6V power line. Will this physically damage MCU or will ...

I have received an email that I missed my confirmation email, but I still would like to join the online workshop. “Driving innovation in ... with STM32 LoRa-enabled ..."

HiI did not got the second E-Mail you send me. Please invite me onec again. Hope it works
