NUCLEO-WL55JC1 Default Factory Option Bytes
What are the option byte settings set to when they ship from the factory for the NUCLEO-WL55JC1?While trying to get the LoRaWAN_SBSFU_1_Slot_DualCore application running somehow I've managed to mess up the boot options. I want to restore them to the...
Resolved! Can't flash firmware/FUS on Nucleo-WB15CC
I was able to flash the board successfully many times but it suddenly stopped working when I changed something in the write protection settings. I think it was "WRP1B_END" which is currently 0x0807f80, but I don't remember the default value, maybe so...
What type of balun can i use for stm32wle5 433mhz?
Hello,I have to create a pcb for stm32wle5 for Lora 433 mhz ( 2 layers, hp) But in references I didn't find any balun for this frequency. Only for 490+ mhz.What balun can I use for 2 layer 433 mhz?With regards
Resolved! Change NUCLEO-WL55JC1 antenna
Hi, I'm implementing a LoRa network (not LoRaWAN) using NUCLEO-WL55JC1 boards in a Master-Slave topology. I've scattered 7 end nodes, i.e., slaves, throughout 150 hectares and achieved successful data transmission. Each of these slaves and their rela...
Resolved! How to use P-NUCLEO-LRWAN2 or NUCLEO-WL55JC1 as gateway and send datas with client not TTN or LORIO.
Hi everyone, I am beginner of stm32. I was using arduino with other lora devices but they consume a lot of power. I was programming lora (ebyte) with HAL_UART. So it was really easy.Since I want to learn to program stm32 and I need really really low...
WL55 Option Byte Programming Failed
Dear Community,I have exhausted all possibilities to find the reason to successfully configure Option Bytes on STM32WL55.With the process I am using CubeProgrammer v2.13 and I can say thatfor STM32WLE5 the programming of OB was successful every-time!...
Reading and calibrating output from STM32WB die temperature sensor
Greetings,This is surprising because it should be a simple task. We've read from the die temperature sensor on other STM32 MCUs without issue. In this case, we are using the STM32WB55MMG module. We can read a calibrated value for the 3.3V VDDA inp...
Resolved! STM32WLE immediately exist Stop2 when using UTILS_ENTER_CRITICAL_SECTION()
I am doing a LoRaWAN project on the STM32WLE and so I want to power it down in Stop2 mode to lower the power consumption.Using the following code, this works fine : UTILS_ENTER_CRITICAL_SECTION(); ...
Can not connect STM32WB55CGU6 with ST link
I'm using STM32WB55CGU6 (UFQFPN-48) for a design and trying to connect with the ST link. But seems like it is not connecting in any way. Can anyone tell me how can I connect this MCU and upload the firmware to this MCU? Why it is not responding?
STM32WLE5JCI6 all bands activation
We are probably need a support from the ST team with the implementation of the LORA (STM32WLE5JCI6) supporting all four frequency ranges.ST has provided two reference designs, one for LB, one for HB. We have combined them together and made it not on ...
