Resolved! WB55: Leaving the chip in the brick after loading the stack. Very important for everyone.

2 years ago it happened that the controller turned to brick. I corresponded with technical support for a long time and I was offered to send the controller to the factory or representative. But since the case was a single one, I did not take advantag...

Wireless Stack recovery for STM32WB

I've gotten my STM32WB55 into a state where CPU2 is booting into a "wireless firmware" area, but I think it's crashing when it starts. I can no longer talk to FUS inside CPU2:------------------------------------------------------------------- ...

Resolved! STM32WB getDescriptor UUID 2902 returns null

I successfully implemented a service with different characteristics. However on the android side when I call getDescriptor()descriptor =characteristic.getDescriptor(UUID.fromString(CLIENT_CHARACTERISTIC_CONFIG)); CLIENT_CHARACTERISTIC_CONFIG = "00002...

Resolved! STM32wb15 is not advertising

I'm starting with the wb15. For this I followed the video series and currently I'm stuck at https://www.youtube.com/watch?v=lFDMBeJpib0&list=PLnMKNibPkDnG9JRe2fbOOpVpWY7E4WbJ-&index=15Even following every step in the cube setting I'm not getting any ...

Followed this video by STmicroelectronics (STM32WB15CC) for simple BLE server(custom). After following exactly same steps I can not Successful Fast Advertisment on Tera term of BLE while in video his BLE started advertising.

The NUCELO-WL55JC2 433MHz transmission is greatly attenuated with LPO, but works at range with HPO. Is that a known issue?

In my testing, I programmed two NUCELO-WL55JC2's to communicate with one another. I found that I could only receive if the transmitter antenna was aligned and touching the receiving antenna.After further debugging, I traced the issue to the LPO.Using...

Aci_gap_set_discoverable() returns Command Disallowed after long period of execution (100+ connections, wakeups and advertisements)

I've been experiencing an issue where sporadically the aci_gap_set_discoverable fails to start due to a command disallowed error (similiar to this) on the STM32WB50.For context: the device goes into sleep mode and wakes-up 100+ times per day. In slee...

I'd like to use a STM32WL55 or B-L072Z-LRWAN1 as a 'beacon sniffer' and 'packet sniffer'.

I'm busy debugging the RF conditions around my LoRaWAN installation.I get a lot of variance in both RSSI and SNR (+-10dB/+-6dB) and am trying to find it's source.In the absence of an SDR and other equipment, is it possible to read and report RSSI an...

B-L4S5I-IOT01A discovery kit - demo app

HiI just bought a B-L4S5I-IOT01A Discovery kit.Confession: I am completely new to ST, and I reckon I have a mountain of learning to do in a short time.However, I just read the blurb on the back of the kit and it essentially says: 1. Verify the jumper...

Resolved! STM32WL5x device errata clarification needed for DMA stream locked when transferring data to/from USART

The errata sheet ES0500 - Rev 4 mentions a workaround for 2.8.3 DMA stream locked when transferring data to/from USART where bit 20 of register DMA_SxCR shall be set. This register is not mentioned in the reference manual and not in the respective he...
