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...
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 ...
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...
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...
Hello,I'm using the STM32WL55 for LoRa communication.I found out that when receiving a packet the RX IRQ from the transceiver is executed in a delay from when the packet finished transmitting.From my tests this delay depends on the channel configurat...
Hi,I have found some questions and discussions with similar topic, but no answer seems to apply to my case. I have an STM32WB55 Nucleo Pack, and I cannot manage to load any of the BLE stack binaries provided with the STM32Cube_FW_WB_V1.16.0 into my d...
Hi all,I'm here beceause I have a question about STM32WL55, I have this board STM32WL55JC and I I look in CAD ressources in schematic file , there is a switch to chosse between High or Low power emission and receive mode. This switch U7 is is ordered...
I am developing a FreeRTOS project with around 12 tasks, many of which use the open thread ot* functions. However, my program will occasionally deadlock on all OpenThread commands, with the stack for each task showing that it is waiting for "Wait_Get...
Hi, Context:I am currently developing a LoRa board implementing the STM32WL55. I didn't get the SubGHz Middleware to work, so i implemented the approach as detailed in the reference manual page 206. The code compiles, and the tx-complete interrupt is...
I am using the STM32WB55RG MCU, Bluetooth feature with stack version 1.13.0 and FUS version 1.2.0. Everything was working normal until I tried doing the firmware upgrade of stack from v12.0 to v13.0. I am not able to perform FUS related operations. T...
