Error Message while transmitting and receiving in STM32WLE5 (LoRa P2P).
Hello Community,I have made a custom board for the LoRa application for both P2P as well as LoRaWAN modes. The reference for the RF network I referred to is "Highband High Power" from the MB170 schematic. The frequency I am making this module is EU86...
Resolved! Wrong pin definition in datasheet of STM32WB5MM
In datasheet, pin 43 as PB0 and pin 44 as PB1. However, it is reversed on the module.
STM32WB55 doesn't remain in STANDBY mode
Hello,I'm trying to put the STM32WB55 into standby mode and eventually wake it up using wakeup pin 1 (PA0), but it wakes up directly after the HAL_PWR_EnterSTANDBYMode() is executed. After that, I checked the PWR->SR1 and it had BLEWUF bit set, but I...
Resolved! Is DMA able to access external FLASH in memory mapped mode?
I am fiddling with a STM32WB5M discovery kit.This kit includes a QuadSPI external NOR FLASH chip and i need to understand this in order to make early design choices. Could the DMA access that external FLASH memory space?I didnt try it yet, but my lim...
Hello, what are the constraints when reprogramming the ARR register in the LPTIM peripheral? E.g. does the counter need to be stopped, or can it be running? Does the ARRM interrupt get triggered only if CNT==ARR, or also for CNT>ARR?
I could not find a definite answer on the STM32WBx5 reference manual.I am setting the LPTIM to generate a periodic interrupt by configuring the ARR register, say to 1 millisecond period. Occasionally, I need to reprogram the ARR with a longer period,...
STM32WB55: DTM/aci_hal_tone_start not activating
Hi, I try to start a a continuous waveform (CW) from the STM32WB radio using theaci_hal_tone_start command from the DTM suite. I execute the following commands:hci_reset( );HAL_Delay( 10 );aci_hal_set_tx_power_level( 1, tx_pow );aci_hal_tone_start( R...

Resolved! STM32WB + option bytes setting
Hi,For stm32wb flash operations we have to implement diagram described in AN5289, page 36. How about option bytes access? Do we have apply the same approach, with semaphores etc? Or we just can use regular HAL functions? Best,Mateusz
Resolved! How fast is EXTI in Stop-Mode and can I make it faster?
My expectation was that a pin-interrupt using EXTI will lead to wakeup times just slightly longer than the wakeup delays named in the datasheet (below 10µs), but what I see is this (falling edge on yellow finally reached the ISR on the magenta rising...
