Hi Hung Bui,

In fact, the Lightblue app did not update the device profile after I uploaded my new code. When I removed my device and stopped the app, and then started again, the characteristic was showing with the user description So problem solved!

Hi Wim,

I don't see any problem with your code, it worked on my side. Could you double check ? You can just leave char_md.p_user_desc_md = NULL;

Which error do you have when running your code ?

That is how I do it, here is my code:

if (description && *description != '\0')
{
    char_md.p_char_user_desc = (uint8_t*) description; // discards const 
    char_md.char_user_desc_size = strlen(description);  
    char_md.char_user_desc_max_size = char_md.char_user_desc_size;
}

I also played around with setting the char_pf stuff, but lightblue ignored it. Having the description text is useful for debug, not sure if I will leave it in the production firmware.
