I'm using a custom board with the STM32WL5MOC. I've noticed that the last three 32-bit words of the OTP have been written to the values: FF FF FF FF FE FF FF FF 02 00 10 38 D1 DB AF 46This makes the OTP 16 bytes shorter. Is this intentional, or is it...

I've noticed what seems to be a bug when writing to flash with the '-w32' flag using STM32_Programmer_CLI. My order of operations is:I erase sector 0 of the flashI read the first 8 words of Flash and verified that it's erased.I write some words to fl...

I'm working on a new design with the STM32WL5MOD and ran across a few questions from the datasheet.The datasheet indicates, "Filtering capacitors on power-supply pins and components for the SMPS are already integrated into the module." The schematic ...

I'm using a CR95HF NFC reader (a Mickroe RFID Click) using the UART port. I'm using ISO 15693 to communicate with my tag. I'm issuing the following commands (I know it looks like I'm using the eval board, but I'm actually using my own Python program:...

I'm using a STM32WLE5 processor in my design. I had an RF consultant tell me that I needed to add a SAW filter to the design to protect against potential interference with 800 MHz cell phone transmissions so I placed a B39921B3728U410 SAW filter at t...

I apologize to everyone for the snarky post. It was uncalled for. I had a fundamental misunderstanding of the purpose of the forum. In the future, I'll take the approach that @Tesla DeLorean suggested.

I can only assume that the module development team at ST does not read this forum...

I wonder if this is done intentionally. There doesn't seem to be any way to distinguish between the module and STM32WLE5/STM32WL5x IC. This would be helpful for me as I'm migrating from the Seeed Studio Wio-E5 that uses the WLE module. They are diffe...

I do realize that flash writes are done 64 bits at a time. I just thought the programmer would take care of this. If writes aren't supported, the tool should simply provide an error.

64-bit works with the following caveat: the high and low 32-bit words seem to be swapped. For example, if I do:> stm32_programmer_cli -c port=SWD mode=NORMAL reset=HWrst -q -w64 0x08000000 0x0807060504030201When I look at the memory file, I see the f...
