Ch582 ble 5.0 uses Le coded broadcast and connection

One 、 Get information

1. obtain SDKhttps://www.wch.cn/search?t=all&q=CH582
2. Revision reference https://www.cnblogs.com/debugdabiaoge/p/16205973.html

Two 、 step

1. Examples of use ：EVT\EXAM\BLE\Peripheral

2. stay Peripheral\APP\peripheral.c Of Peripheral_Init Add... To the function

           uint8 initial_adv_event_type = GAP_ADTYPE_EXT_CONN_UNDIRECT;
           GAPRole_SetParameter(GAPROLE_ADV_EVENT_TYPE, sizeof(uint8), &initial_adv_event_type);
           GAP_SetParamValue(TGAP_ADV_SECONDARY_PHY, GAP_PHY_VAL_LE_CODED);
           GAP_SetParamValue(TGAP_ADV_PRIMARY_PHY, GAP_PHY_VAL_LE_CODED);
           GAP_SetParamValue(TGAP_ADV_SECONDARY_MAX_SKIP, 0);
           GAP_SetParamValue(TGAP_ADV_ADVERTISING_SID, 8);
   

   What we use here is 125K Rate
   The changes here , You can refer to the example ：EVT\EXAM\BLE\SYNC_ADV

3. If you need After connection , Slave machine PHY Negotiation of , Can be in peripheralStateNotificationCB Of case GAPROLE_CONNECTED Add negotiation tasks

   case GAPROLE_CONNECTED:
       if(pEvent->gap.opcode == GAP_LINK_ESTABLISHED_EVENT)
       {
         
           Peripheral_LinkEstablished(pEvent);
           PRINT("Connected..\n");
           tmos_start_task(Peripheral_TaskID, SBP_PHY_UPDATE_EVT, SBP_READ_RSSI_EVT_PERIOD); // Start negotiation PHY  there SBP_READ_RSSI_EVT_PERIOD  Just random , Use it 
       }
       break;
   

4. If you need to increase power , You can modify config.h Of #define BLE_TX_POWER LL_TX_POWEER_6_DBM

3、 ... and 、 result

You can see PrimaryPHY and SecondaryPHY All are LE Coded
Notice that you can't see the name here , It is necessary to modify the broadcast package , Here you can refer to EVT\EXAM\BLE\SYNC_ADV Modify the broadcast package , I haven't done the next research for the time being
