Part Number: LAUNCHXL-CC2640R2
Other Parts Discussed in Thread: CC2640, CC2650

Trying to implement an iOS app that performs OAD on CC2640.

Wrote 01 00 to FFC1

Wrote 01 00 to FFC5

Wrote 01 to FFC5, returns 01 14 00

Now when I write the image header to FFC1 , I get a return value of 0b, instead of 00.

I am sending a 16 byte packet( 5c3affff 00002f25 45454545 000001ff) - the same format that I used for uploading image header for OAD with CC2650. Quite likely, this format is incorrect.

Could someone please share sample code as to how to create the image header packet for cc2640?

Thanks!

Thank you. I looked at the BTool logs. Here is what it writes to Image Identify as header:

4F:41:44:20:49:4D:47:20:01:01:FF:FF:01:01:BD:94:00:00:30:30:30:32

However this doesn't include all header fields as listed in http://software-dl.ti.com/lprf/simplelink_cc2640r2_latest/docs/blestack/ble_user_guide/html/oad-ble-stack-3.x/oad_profile.html#oad-image-header

Send Metadata To ImageIdentify returns success though. The length of image header in this case is only 22 bytes, whereas according to the documentation it should be 76 bytes.

Is it not necessary to send all the image header fields ?

Thanks!
