RN-42 Firmware Truncation

[rupin]

When I chose the RN-42 Firmware available here https://drive.google.com/file/d/0B2oHzSfiLL8PdU1tWmhvS19EWG8/view

Blueflash Reports that the image size is bigger than flash size, and the firmware gets truncated.

"Image size is greater than Flash Size. Image will be truncated"

The upload happens, but PS Tool does not list the data from the persistent storage.

If anyone has seen this issue happen, please advise how to solve it.

See issue #25

BTW, while counterfeit modules described in #25 are based on a relabeled "BC3 MM" chip (codenamed "KAL") and have 1 MB flash, your module is based on a "BC3 Audio Flash" chip (codenamed "PDW"), which is somewhat newer than KAL, but looks like it has less flash memory. It would be great if You can provide more info about your module, such as pics, output of "e2cmd.exe info" and "BlueFlashCmd.exe identify", when run in a terminal. Whether it was marketed as HC-05 or HC-06?

Bought HC-05 https://a.d-cd.net/FgAAAgKOXuA-1920.jpg it has Spansion AL008J70BF102 flash.
