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...
Resolved! Booting from Flash memory not working with STM32WB15CCU6
Hi, I've got an STM32WB15CCU6 on a custom board and am currently trying to get it to boot from Flash memory after programming it with the STM Cube IDE.Debugging a program in the IDE works perfectly fine, but if I flash it to my microcontroller (using...
Resolved! Pingpong subGhz dual Core Example
Hello I have two STM32WL55JC2 boards and I would like to run the PingPong DualCore example available in this WL package folder : I run the .project file on the STM32 IDE and I get this: After adding several missing .h files I manage to flash to the b...
How to send multi packet and is there any example?
I want to send 2 kbyte data using BLE in WB55.Becasue the packet size is limited to 245 byte (it may be 509 byte if change ATT-MTU to 512 but still I couldn't make it.)So, I wonder whether there is good example for this.Could you suggest anything?
How can I check the ATT-MTU of the current connection (not setup)?
How can I check the ATT-MTU of the current connection (not setup)?What coding can I use to check? For example, I want to return ATT-MTU size through USART after measuring it in the microcontroller.
