I cant connect to BLUENRG ST link utility , i have made all connections properly, can anyone tell me what they think i have to do to make it work.

[CNaha.1]

Pin connection:

ST link ------ BLUENRG232

SWDIO SWDIO

SWCLK SWCLK

GND GND

3.3V VCC

I have also made IO7 high with 10K resister To GND.

Pls. help me out.

Hi,

could you please detail a bit more your setup and needs?

If you need to update the BlueNRG-2 module firmware of X-NUCLEO-BNRG2A1, we would suggest to refer to the procedure reported in section 1.2.2 of this guide.

Hope this can help.

Kind regards

hi

all i need help is

• Firstly,

I have not buy any board of your BLUENRG evaluation board.

I am using IC and supporting Circuit.

• Secondly,

My Problem is that can you tell me what changes I have to do with software or hardware to make it run.

I will make you understandable through this.

I have BLUENRG232 IC (https://www.digikey.in/product-detail/en/stmicro/BLUENRG-232/497-17582-1-ND/7565506?cur=INR&lang=en&utm_adgroup=RF%2FIF%20and%20RFID&utm_source=google&utm_medium=cpc&utm_campaign=Smart%20Shopping_Product_RF%2FIF%20and%20RFID&utm_term=&productid=7565506&gclid=CjwKCAjw0On8BRAgEiwAincsHAUyGWwc01w4edFI8TV9pMPrf-0No1wSfc2aASG-95pkZ7K0-41JhBoCi5IQAvD_BwE)

Tell me its supporting circuit and how to upload code to it and debug using BLUENRG1_ST_LINK_UTILITY ?

Hi,

section 3.21 of this Datasheet reports the SWD debug feature.

look I tell you what I understand,

I have to connect IO7 to GND(and other pins of course) and it should work.

but even though its not working.

Can you read the datasheet and tell me what I am doing wrong?

should I have to connect some other components to IC to make it work?

I am having the same problem. I made PCB with supporting circuit for BLUENRG. The St link utility is not detecting the target.

[pankajauengg]

please share the setting we need to make for target in BLUENRG ST link utility

I gone through the section 3.21 of this Datasheet reports the SWD debug feature. But sill not resolved the issue. Please help me.
