    OTA speed checking with 20737S BLE4.0 SOC?

      Description:

         

      We test our application code (size~ 30KB) together with original hello-sensor sample code (size~8KB);

         

      we find ota time of T(hello-sensor) is Ta  and our application code is Tapp where Tapp > Ta too much.

         

      We observe the reason why Tapp is bigger than Ta is owing to code size during OTA wireless transfer and
      synchronous program/erase speed dependent of code size. Besides that, any other bug/reason we can
      improve the OTA speed from handset side?

         

      Besides, OTA speed seems to have something to do with OS system on handset like android phone/iOS phone;

         

      how to prevent OTA speed change if user upgrades a higher version OS on phone?
