Hello everyone,I am working on B L072Z LRWAN1 kit, in which murata LoRa Module is used having STM32L072 controller. I am trying to implement low power modes and running the example code :STM32Cube\Repository\STM32Cube_FW_L0_V1.11.2\Projects\STM32L073...
Hi,I have a project with heavy constrains on power consumption.I want to completely shut down the supply of the LoRa modem when not in use to save the needed µA.The CPU can save any context needed.The NVM module seems to be the way to go.I've seen so...
I'm looking for an AppNote or example showing how to enter STOP2 mode with BLE advertising enabled (low consumption, but BLE advertising). And how to : on any BLE connection, exit from STOP2.
Hi, I am trying to calculate the current consumption for my BL072z board1.- my formula:16mA in run mode30uA in stop modeT to tx data = 20 secsNumber of txs in a hour = 3600/20 = 180duration of each tx = 3 secondstotal TX time = 3(180)=540 seconds = 0...
I have the development board, B-L072-LRWAN1 with the CMWX1ZZABZ-078 module by Murtata on it. This module has an 32.768KHZ crystal on it which will be used for keep the RTC. I would like to implement a wakeup timer using this crystal to wakeup every 2...

Hi, I am having issues reinitialising the BLE stack after waking up from sleep. I am initialising it the exact same was as normal power on. Upon waking up and calling the TL_Enable() function, a shci_notify_asynch_evt it not being received. Is there...
I am unable to successfully put the STM32WB55 into Shutdown mode and then wakeup via either one of the WKUP pins or the RTC. I can get the WKUP pins to work if I use HAL_PWRex_DisableInternalWakeupLine, but then it won't wakeup via the RTC. If I om...
Hello!I come there after some days of work on the stop mode on the dicovery board STM32L0 with LoRaWAN.I tried to generate a new project which does nothing, to test the stop mode with RTC following the datasheet and measure the current consumption. I...
