Hi at all, I'm testing the bluetooth classic SPP profile as in example folder (bt_spp_acceptor), it works! But I have noticed that the device is recognized as Speaker or Audio devices.
Is possible to change the profile (or class?) to a generic type (a generic "bluetooth device" is enough)?

I have tried the

Code: Select all

esp_bt_gap_set_cod

whith

Code: Select all

ESP_BT_CLR_COD_SERVICE_CLASS

without difference.

Someone can help me?

Thanks!

I have solved!

I have to set all the minor, major and service

Code: Select all

        class.minor = 0b000101;
        class.major = 0b00001;
        class.service = 0b00000010000;

        esp_err_t ret;
        ret = esp_bt_gap_set_cod(class, ESP_BT_INIT_COD);

In my case, I could set the service class but could not set the major and minor device class, any suggestion ?
