This is my first foray into STM32. I bought a couple of WIOE5 lora modules. This post will not let me post links to the the WIOE5 datasheet.
I bought an STlink V3mini from Waveshare. There is not a datasheet available. I now see that my actual st link does not have side pins.
I downloaded STM32 Cube Programmer.
I have read that before using the Arduino IDE to program the STM32, I need to install a bootloader via cube programmer.
While trying to upload a bootloade via cube programmer, I have a steady 3.3 volt power supply going to my MCU/pcb. My understanding is that the STM32 mcu needs to be externally powered before using the STlinkV3. When powered, I can confirm with a DMM that I am getting about 3.27 volts to the STlink. The cube programmer says that my target voltage is 3.25 but it will not connect.
The error message is “No STM32 target found! If your product embeds debug authentication, please perform a discovery using Debug Authentication”.
The WIOE5 module is brand new, never been programmed before. I want to use the ARDUINO ide, and have added the STM32duino core from ST electronics.
The ST link is also brand new. never used. I have tried the usb cable that came with the st link, and also a known good one that I have used for programming arduinos on the past.
The project is this: I wanted to make a long distance (a few hundred feet) remote control for my gate operator. This is the transmitter part. I designed a pcb that fits into a housing I already have. I also made a small pogo pin clamp that clamps to my programming header pin.

Any thoughts on why I can’t get the cube programmer to connect? Or do I even need it? I am a rookie at STM32, (and electronics in general) so talk to me in layman’s terms.
When trying to post, I had to add a specific board and series. The STM32 is STM32wle5, i think, but that is not an option in the labels to check. So I chose bootloader, since that is what I am attempting to do.
Thanks.
