spp handle id

[peterlspot]

How SPP handle is managed in SPP acceptor role?

It seems that the handle value got upon ESP_SPP_SRV_OPEN_EVT is not always the same as the handle upon ESP_SPP_CLOSE_EVT.

Code: Select all

case ESP_SPP_SRV_OPEN_EVT:
     ESP_LOGI(TAG, "srv_open: %d", param->srv_open.handle);
     break;
case ESP_SPP_CLOSE_EVT:
    ESP_LOGI(TAG, "close: %d", param->close.handle);
    break;

Sometimes the two values are same, sometimes they are not. Not sure how handle is defined and managed in ESP_SPP module. Can someone teach here?
