CC2540 module

Other Parts Discussed in Thread: CC2540

Hi,

I have used the CC2540 mini EMK for a project with the iphone.
Everything was working all right.

Now i bought some extra modules to expaned the BLE are but the program on the iphone is getting stuck when i use the new modules.
I copied the hex file from the old module to the new CC2540 module. It works with the old CC2540 module (bought last year) but with the one bought this month the program crashes.

Is there made a change to the board of the CC2540 or do i need an newer ioCC2540.h file ?

The "old" version is 1.5.1 / CC2540DK_EM.
On the newest the version is CC2540DK_EM / 1.5.1.1

Kind regards,

Davy

Davy,

This is rather strange, the CC2540EM has not changed much except for the crystal loading caps which have been changed to 12pF.

Do you have an updated version of the stack?

Hello Chatto,

I have the same issue on my second CC2540DK-MINI as well. Please see my thread below.

I use old and new stacks on my old CC2540DK-MINI, it works fine with iPhone.

But I run either stack on new CC2540DK-MINI, it always stuck.

Regards,

Alex

Hello,

I use the stack version 1.0 .

I do this because i need to buy a new version of IAR to compile the newer stack versions.

I don't know if thisis the problem.

Else i try to compile the project with the new stack with a time limited version of IAR.

Thanks,
