Cannot find LoRa PingPong example. B-L072Z-LRWAN1 (or other L0 resources)

Hello everyone. 4 years ago i began developing a project from this board B-L072Z-LRWAN1 using a LoRa "PingPong" example. Now i want to re-start this project on Nucleo-STM32WL55, but there is not a "LoRa PingPong" example, only a SubGhz PingPong (alas...

STM32WB55 - Data length extension supported with CFG_BLE_DATA_LENGTH_EXTENSION = 0?

HiWe have a project that uses the STM32WB55 with the full BLE stack in version 1.10.1. Today I recorded some air traffic between my PC and the device and struggled over something that confused me.In our project we have disabled the data length suppor...

Trouble running a successful LoRaWAN FUOTA campaign on a Nucleo-WL55JC

Hello,I am having trouble running a successful LoRaWAN FUOTA campaign for my Nucleo-WL55JC development board. I am using the LoRaWAN_FUOTA_DualCore example project found in the STM32CubeWL_V1.2.0 firmware package, and am using AWS-IoT for LoRaWAN as ...

STM32WB15 SWD interface disable

Hi,On a custom board I can no longer reprogram the MCU (STM32WB15) via the SWD link.The last program flashed on the card works perfectly but I can no longer establish the SWD link with CubeIde via the ST-LINK probe.Message "target not found".I guess ...

Resolved! I cannot start debugging STM32WB55VGY6TR using ST-LINK inside the Nucleo-WB-55 board. The IDE said that failed to start the GDB server and error in initializing the ST-LINK device.

I'm developing my custom board using a STM32WB55VGY6TR microcontroller and I want to use the Nucleo-WB55 developer kit as a programmer for my custom circuit board.However, I cannot start debugging using STM32cubeIDE. The IDE said that failed to start...

Resolved! Hi, Colleagues I created my PCB board with stm32wb55cgu6 for transmitting data via BLE and want to check this design. Maybe who has a .hex file for BLE transmission to the mobile phone, I need only detect in my phone whether this board a visible or not

STM32WLE5CC ADR Backoff doesn't change tx power.

Hello,In STM32WLE5CC Lorawan, when It Doesn't get ack for confirmed uplink, it decreases its datarate(Increase SF), but not TX Power is increases.Say Due to ADR Device is at DR5 and TX Power 10. Due to increase in noise, device doesn't get ack from L...

Resolved! How can I know the GPIO_Typedef of a Pin?

I connected a LED to the PA11 pin of STM32WB55VGY microcontrollerand I want to toggle it.So, I'm trying to use HAL_GPIO_TogglePin(xx, yy) but I cannot know the "xx (GPIO_Typedef)" of PA11 pin.Where can I found which pin is which GPIOx?

Resolved! STM32WB10 ADC DMA needs more regular channels

Hi,I am developing a small module with the STM32WB10 and I need to do 10 ADC conversions (9 external and the internal temperature).However, I can only get the DMA to do the 8 channels configured in the regular channel ranks (Number of conversions = 8...

Resolved! Where is the Downlink receiving and processing function?

Hello everyone,Currently, I am working with the example LoRaWAN_End_Node on Nucleo-WL55JC1. I am trying to achieve downlink control. Downlink messages are sent from Chirpstack NS.Right now, I don't know where the function of receiving and processing ...
