[GitHub] [mynewt-nimble] danimasa opened a new issue, #1363: Dynamic characteristics

danimasa opened a new issue, #1363:
URL: https://github.com/apache/mynewt-nimble/issues/1363

   How can I create `ble_gatt_chr_def` dynamically at runtime?
   
   All the examples show a static array of `ble_gatt_svc_def` already with the characteristics. In my case I'll only kwown the caractheristics information at runtime. I've tried to change the characteristics pointer to a different array after creating a static global variable but the characteristics was not listed in BLE Service.
   
   I'm doing like that:
   ```c
   static struct ble_gatt_svc_def gatt_svr_svcs[] = {...};
   
   void start()
   {
       struct ble_gatt_chr_def chrs[chr_count];
       for(int i = 0; i < chr_count; i++)
       {
           struct ble_gatt_chr_def chr = {...};
           chrs[i] = chr;
       }
       gatt_svr_svcs[0].characteristics = chrs;
   
       ble_gatts_count_cfg(gatt_svr_svcs);
       ble_gatts_add_svcs(gatt_svr_svcs);
   }
   ```

   I used micropython as a reference to generate de services at runtime.
