Why does OTA download not save the file in flash?

The BL652 supports over the air (OTA) smartbasic downloads. To put the BL652 development board into OTA mode set J12 low and connect J5 and reboot the development board If instead of saving the downloaded file to flash you see the OTA commands being output from the module UART then the module will be in VSP bridge and not VSP command mode, please check J12 is set correctly. Note that if J12 is set high then the DTR tick box (USB DTR) in UWTerminalX controls autorun and therefore VSP Bridge/Command mode.
