I tried flashing PWR_STANDBY_RTC and PWR_EnterStandbyMode examples both has sleep current of 590uA. How do i get the datasheet value of 600nA standby current or atleast something less than 10uA.

I have gone through the course pre-requisites but have some queries. I cannot communicate to the STM32WL55 via comm port which is preventing me from making progress ahead of the course. Full details listed below, many thanks in advance for you support.

I have started to go through the course pre-requisites and am familiarising myself with the kit and feeling much more confident, particularly as I have the gateway setup on TTN an seeing the L073RZ dev board ping in. I am still going through the prer...

Resolved! Bootloader to update firmware via UART: It is possible to invert UART TX pin?

My project requires a RS-232 cable with TX inverted to connect the PC with CubeProgrammer CLI to STM32WB55. In application, I am able to configure the UART with "UART_ADVFEATURE_TXINVERT_INIT", and the STM32WB55 transmission works fine through the RS...
