How to make STM32WB bluevoice demo work.

[jeffl.kelley9]

STM32WB55 bluevoice demo. Peripheral blinks blue, but turns red on SW1. Central blinks green -- on reset of central peripheral returns to blinking green. No code changes, but yesterday green blink was rapid today slow. I can't ask good questions yet because I am trying to figure out how this works, but I need it working to do that. Any ideas?

Hello,

Informations about STM32WB55 BlueVoice demonstration are available on ST website:

https://www.st.com/en/embedded-software/fp-aud-bvlinkwb1.html?ecmp=tt9470_gl_link_feb2019&rt=um&id=UM2614#documentation

In user manual (UM2614) page 15, you have some informations about led status:

• advertising/discovery: green LED blinking

• connection: blue LED slow blinking

• streaming: blue LED normal blinking

• Receiving: blue LED steady on (not blinking)

• Full-duplex: blue LED fast blinking on both modules

If red LED turns on, an error occurs.

Best Regards,
