I bought the shield bluetooth 4.0. ( zbmodule)
First, In the product description, the using chip is TI CC2541 but on the shield that I have, the chip is TI CC2540.
I want to use the chip in Master mode so I update a new firmware on the chip. The update procedure is ok but the chip don't work.
I have try with two firmware : HMSoft_cc2540.bin and HMSoft_cc2541.bin
So Is it possible to change in Master mode with another firmware?
If is'nt possible, can I find the original firmware because to day the shield does'nt work ?
Can you help me please.
