I have a problem with the name of the device when playing advertising. I named it VCONNEX_MESH_XXXX. But when playing the adv, the name is not displayed, when I connect to the device, it displays the name.
Your name is only set in the ATT table, which requires a successful connection to retrieve it, as expected. The contents of the ATT table are read through the service discovery process after a successful connection. Before connection, it will not be read.
