InfiniteYuan opened a new issue #1220:
URL: https://github.com/apache/mynewt-nimble/issues/1220


   # Problem Describing
   
   Can't alloc os_mbuf when a lot of data needs to be proxied in BLE-MESH, so `om` is null to cause crash(assert).
   
   static int proxy_send(uint16_t conn_handle, const void *data, uint16_t len)
   ```
   BT_DBG("%u bytes: %s", len, bt_hex(data, len));
   om = ble_hs_mbuf_from_flat(data, len);
   assert(om);
   err = ble_gatts_notify_custom(conn_handle, svc_handles.proxy_data_out_h, om);
   notify_complete();
   ```

   These are also handled with assert: [pb_gatt_srv.c#L410-L411](https://github1s.com/apache/mynewt-nimble/blob/master/nimble/host/mesh/src/pb_gatt_srv.c#L410-L411) and [proxy_srv.c#L876-L877](https://github1s.com/apache/mynewt-nimble/blob/master/nimble/host/mesh/src/proxy_srv.c#L876-L877). We should reconsider how to deal with it.
