Is there any other way like i can set in simple OTA to prevent someone to upload any other firmware(bin file) ?

Hi,

You can always write protect the pages in flash using SmartRF Flash Programmer.

Thanks Zahid Haq !
I am working on OTA. I have created Super Hex file(BIM+ImagA) and OTA File(ImagB.bin).
Now my question is what settings() I should make that device(with super hex file) ONLY accept my bin file(Not Others).
How can i add (sign in like aesKey) in simple OTA portion ?

Hi,

Changing the aesKey is described in page 15 of the CC254x OAD guide:

Thanks for reply Zahid Haq
That aesKey described in only Encrypted OTA . I want to do that in simple OTA ? Can i define aesKey in simple OTA Files?

I suppose there’s no encryption in simple OTA and if so, what’s the logic to define aeskey?

Zahid already suggested you to use Use OAD Encrypted Img projects as in SimpleBLEPeripheral.

But i am stuck at these point(Unable to connect device with BTool)

Can I bypass these steps to complete Encrypted OTA?

Can I use this to sign in simple OTA. If NO kindly suggest me something unique in Simple OTA to stop to upload any bin file except mine.
