Issue while creating multiple service in BLE GATT service table example

Postby Ashvajit.P » Tue Aug 16, 2022 9:03 am

Hello,
i want to add multiple service in the given BLE service table example. I tried to create another table and created attribute table manually, but before staring the 2nd service my device starts advertising and after connection I am not able to see the 2nd service that has been created.

The event after creating first attribute table

Code: Select all

        case ESP_GATTS_CREAT_ATTR_TAB_EVT:{
	        static bool SEC_service_Created = false;

	        if(0 == RB_service_handle[IDX_SVC])
	        {

			        }
		        }

	        }
               
	        	        
            break;
        }
Is there any example or reference from where I can see multiple service added by using service table ?
