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 ...

Resolved! Spurious BLE disconnection

Hi,I am using two device that are connected one to another with BLE.The first device is a server.The second is a routeur.I detect some spurious disconnection between both device after some random time.The disconnection error I get is : HCI_CONNECTION...

What is the maximum value of HS_STARTUP_TIME for BlueNRG-1?

Hi friend,I want to extend the HS_STARTUP_TIME for BlueNRG-1. What is the maximum value of HS_STARTUP_TIME for BlueNRG-1? I saw the datasheet AN4494 it says that "XTAL_startup = XTAL_startup_measured*1.2*1.1*1.3 = 1.716*XTAL_startup_measured". So 19...

Does anyone have NUCLEO-WBA52CG board MB1863/61 schematic?
