I am using the NUCLEO-WL55JC1 board to transmit LoRa 868MHz using low-power mode (14dBm). However, when I measure the signal in a noise free radio lab, the received signal power is incredibly low - has anyone encountered something similar?

Details:TX Power on Board: 14dBm (LP)Omnidirectional TX antenna (on board): 2dBiDirectional RX antenna (LPDA): 4dBiDistance: 0.5m free space with minimal interference in labFrequency: 868MHzFSPL (868MHz @ 0.5m) = -25dBExpected P_ in RX: -5dBmMeasure...

STM32WB55 Changing SPI CPHA on custom board doesn't change clock phase

Hello ST team,We're having an odd SPI bug with our custom board.We made a board based on the STM32WB55, everything seems to work fine except for this issue.We're trying to use the spi in mode 0 (CPOL=0 CPHA=0) , but we can't make it work.We have thes...

How to select the transmitting power mode based on region(EU868) for stm32WL?

Hello community,I am designing the STM32WL module for the EU868 (south Africa) region based on the LoRAWAN application. As per the datasheet of stm32WL, the max power used in transmitting is 14 dBm @ 868MHz, so with the reference from the Lora-allian...

Resolved! LoRa-E5 mini (STM32WLE5JC) programming using STM32CubeIDE

Hi,I am using LoRa-E5 mini board from seeed studio (https://www.seeedstudio.com/LoRa-E5-mini-STM32WLE5JC-p-4869.html)To program it using STM32CubeIDE, do we need to connect it to pc using ST-Link or we can simply program it via Type C cable?

53L5A1 SimpleRanging example code timeout error

I am trying to get the simple ranging example code for the 53L5A1 to work on the WB55RG board but I keep getting a timeout error.The text output the example code outputs is "L53L5A1_RANGING_SENSOR_Init failed. Check you're using ONLY the center devic...

How to control LSI in zephyr STM32WB55RG(nucleo board)

Hi allSTM32WB55RG nucleo board zephyr (3.0)When BLE stack is enabled, it becomes halt.Can't I use LSI clock to make the BLE stack run ?We made a sample board, but We didn't attach an LSE.So. use LSI clock. If We use LSE in nucleo , it will behave...

Resolved! Client-Server connection on the same STM32WB device

HIMy STM32WB55 is configured as central and peripheral role.For debugging, Is it possible to establish an internal connection between them?Running two tasks to handle each app.Cheers!
