LoRa-E5 mini (STM32WLE5JC) programming using STM32CubeIDE

[FBrin.1]

Hi,

I am using LoRa-E5 mini board from seeed studio (https://www.seeedstudio.com/LoRa-E5-mini-STM32WLE5JC-p-4869.html)

To program it using STM32CubeIDE, do we need to connect it to pc using ST-Link or we can simply program it via Type C cable?

Hello @FBrin.1​ ,

Connect the STM32WLE5 board to the computer with a USB cable type C to the Type C port for power and serial communication, and connect another micro USB cable to the ST-Link side to the SWD pins.

You can refer to this resources for more help:

• How to build a LoRa® application with STM32CubeWL
• LoRa communication within STM32

Hope this help you!

Thanks Imen,

Can you please clarify this part : "connect another micro USB cable to the ST-Link side to the SWD pins."

Where can I get this ST-Link cable?

Hi @Imen DAHMEN​ 

Can you please clarify this part : "connect another micro USB cable to the ST-Link side to the SWD pins."

Which ST-Link cable should be connected to SWD pins?

Will this work ? https://www.adafruit.com/product/2548

Hi @FBrin.1​ ,

Sorry for the delay to answer you, as this period is very busy for me with many tasks.

You need to connect the ST-LINK to a target using the SWD cable as you can see below.

You can check the SWD pins connections in the UM1075, Table 4. JTAG/SWD cable connections.

I hope this helps !

Hello

You discussed about hardware issue but you didn't talk about the more important!!!! how to make an End Node LORAWAN object that make join and send data to network with the STM32WLE5J8I for example.

NO information and no help on this subject!!!

Thank you for your answer but i want an example for the STM32WLE5J8I and the Nucleo use the STM32WL55 and it's not the same thing!!!
