A problem that adding gzll to ble_keyboard

[Spectre choi]

hello：

      I want to communicate with my nrf25U1 USB dongle. So i add some code（refer to the examples\proprietary_rf\gzll\gzp_desktop_emulator）. When i add add these files(nrf_gzp.c nrf_gzpdevice.c nrf_ecb.c nrf_nvmc.c gzll_nrf52_sd_resource_arm.lib) to my project，I got a problematic file after compiling with keil.i set project IROM start address to 0x26000,but when I used J-FLASH software to open this hex file and saw that the starting address is 0x1000, and the content between 0 and 2000 is 0xffffffff.Should I open some macros？ how to deal this problem. Thanks.

           softdevice：s132_nrf52_6.1.1，SDK15.3.0   hardware：PCA10040

Hi Spectre,

I want to communicate with my nrf25U1 USB dongle.

What is the nrf25U1 USB dongle?

So i add some code（refer to the examples\proprietary_rf\gzll\gzp_desktop_emulator）

What are you doing? Why do you use ble_app_hids_keyboard and Gazell? Gazell doesn't require the softdevice.

Could you run the example without modification?

Hi Amanda，

Thank you for your reply！i am sorry for my unclear description.

i can run ble_app_hids_keyboard when not adding the above file to my project.

 nrf25U1 USB dongle just a module,It uses nrf24u01.

My product needs to use ble-hid mode and 2.4G mode(but they don't work at the same time) .so  i want to use a set of code but can achieve two functions(ble and 2.4G) .

My colleague add Gazell(refer to gzp_desktop_emulator ) to   ble_app_hids_keyboard two years ago and it is work.But at that time he used 51802 and old sdk.

Can't I use ble keyboard and Gazell together?Can you give me some solutions? If yes, is there a demo code?

I'm not good at writing. If my words confuses you, I will try to make it clear.My own project is extended from ble_keyboard ,then  I encountered the above problem when I added gzll.

So I use ble_app_hids_keyboard and Gazell for reproduce the problem.

Just add the above file to the keil project of ble_app_hids_keyboard and compile to get this problematic hex file.

It seems the file gzll_nrf52_sd_resource_arm.lib causing the problem.But when I compile the example of multiple protocols, I get a normal hex file.

hi, I solved my problem today. ：D  

I can see that In nrf_gzp_config.h included by the nrf_gzp.h file there's a variable called GZP_PARAMS_STORAGE_ADR, which is set to 0x1000.

I don't know why the demo（examples\proprietary_rf\gzll\gzp_desktop_emulator） sets it to 0x15000 (if softdevice is used)，How to get it？I set my application start address to 0x26000 because I used S132.

i set GZP_PARAMS_STORAGE_ADR to a address that between application ends and fds.
