Delayed RX IRQ with STM32WL5x Transceiver with LoRa
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...
Cannot load BLE firmware into the STM32WB55 CPU2
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...
Resolved! Where FE_CTRL1, FE_CTRL2 and FE_CTRL3 are used with STM32WL55 ?
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...
Is the OpenThread API concurrent safe?
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...
What are the reception parameters of the nucleo LoRa applications/examples ?
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...
Resolved! Unable to start FUS
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...
Compatibility of firmware compiled with v1.10 libraries and stack 1.16 on STM32WB55CG
Hello everyoneI produce devices on the WB55CG with a BLE stack.There is a working firmware with libraries 1.10.0, everything worked successfully on chips with FUS 1.1.2.0Now a new batch of devices is in production, now in the MCU FUS 1.2.0.0.1) Do I ...
stm32wl55jc adjust adc dma sample rate for microphone
I am using stm32wl55jc1. I want to use accelerometer at 50khz and microphone at 2khz (2048). I am trying to make fft. With pooling adc method, I can do that easily. with 500 micro second delay. for(int i=0;i<128;i++) { microSecond=micros(); HAL_ADC_P...
Hi, I'm trying to transmit information between two NucleoWL55JC1 boards using LoRa modulation, i.e only the SUBGHZ_PHY layer. I want to set up the peripherals and middleware with CubeMX and use the HAL SUBGHZ functions in the code section.
Unluckily, I haven't found indications as to which of this functions to use for a basic transmit/receive application. In the HAL documentation and inside the stm32wlxx_hal_subghz.c file the functions are described independently but there is no cont...
Resolved! STOP2 low power on STM32WB55 with BLE connection wakeup
Hello all,I am running a custom BLE application on STM32WB55 and I want to implement low power STOP2 mode because it's the deepest while RF is still alive. The idea is to periodically wakeup, procced some data and go back to STOP2. I may also need to...
