STM32WL55JC1 sampling rate is different

Hello everyone, I am trying to do tone calculator. I am using DSP , ADC ,DMA and timer for sampling rate. I am using tone genarator and for example if tone is 500 hz and my fftoutbuffer[16] is going high value (noramlly 130 but when tone generate is ...

Can STM32L072CZ be used for LORA. Do they have a LoRa stack?

Regarding RTC update in I-CUBE-LRWAN project

Greetings,I am working on the LoRaWAN Project and facing issues in updating RTC from a server/UART in LoRaWAN library.My code is getting stuck while updating RTC, I am recieving time and from UART through user input.RTC_TimeTypeDef set_time;RTC_DateT...

When "USE_FULL_ASSERT" is enabled in example application "LoRaWan_End_Node" the application stops sending or keeps trying to send, but messages not received at server side.

Just used the example application "LoRaWan_End_Node" with the Nucleo-WLWL55JC board.This example send every 10seconds data to a gateway which is received in the TheThingsNetwork environment. Default is "LoRaWan_End_Node" disabled, when "USE_FULL_ASSE...

[BLE] Read Locally a BLE Attribute

I have created a service and some characteristics with size of 247.I use 'ACI_GATT_READ_HANDLE_VALUE' to read it and I get some weird response.Although I requested to read a size of 200, the command returns only 19 .This is my response packet: and th...

Why on my LRWAN3 node card, when I power it externally on the +E5V tab, the LoRa card doesn't transmit anymore, while when I connect the usb + external power supply it works again?

Why on my LRWAN3 node card, when I power it externally on the +E5V tab, the LoRa card doesn't transmit anymore, while when I connect the usb + external power supply it works again? And why when I remove all the power supplies and I leave the USB cabl...

STM32WBA: Can I receive BLE frame in Ultra low power mode?

Hi,   With STM32WBA52 (or others STM32WBA), can I receive BLE frame with MCU in ultra low power mode? What's the power consumption? Can I set BLE in ultra low power mode and still receive frame? That would trigger and wake up the MCU   What STM32WBA ...

How do I send the data from my external soil moisture sensor by ADC being connected to an ADC input of the B-L072Z-LRWAN1 microcontroller using the I-CUBE-LRWAN1 example on the web or another method?

Hello everyone, I am completely new to the forum and to the world of LoRaWAN on microcontrollers.I am doing my undergraduate final project. This is based on a B-L072Z-LRWAN1 core that has a couple of sensors connected to it. One of them is an ADC sen...

Read data from 3rd party IMU over BLE

Hi, I am using a STM32WB55, and a third party IMU device. I used the P2P client demo code to start, and was able to get the two devices to connect. But I am trying to figure out how to call and read the data now. Since the P2P client app is not se...
