STM32WL5MOC dual output bands.
This https://blog.st.com/stm32wl5x-stm32wl5m/ seems to suggest that the wireless module could be either 900 or 800 MHz bands."Hence, coupled with the wide frequency range supported by its STM32WL5x, the module can work in Europe, Americas, and Asia."...
NUCLEO-WL55JC1 Sleep Mode Current Consumption
Hi, I am using the NUCLEO-WL55JC1 board and referring to the PWR_STOP2_RTC example to measure current consumption. I have isolated the ST-LINK section and am powering the board with an external 3.6 V supply for accurate measurement. However, in sle...
Resolved! DWT timing question
P-NUCLEO-WB55Just a sanity check really.I'm using the DWT unit to time a chunk of code, am I right that each tick is at 1/32MHz?
How to change advertisment data on BLE beacon
Hello. I got my hands on a wba55cg nucleo board and i'm currently studying about ble.I want to create a BLE Beacon that changes its adv_data whenever a user presses one of the button. From messing around using the p2p_server and beacon st examples, i...
Ultra low power consumption using LPTIM
I am using LPTIM for pulse counting in ultra low power (stop 2) mode for STM32wl55jc. Now, the problem is on the pin if I connect any pull up/ pull down with 10k-50k range, it draws significant amount of current. Can anyone please suggest a circuit t...
