looking for example Gazell project on Nrf52840

[Herb W.]

I am looking at using two Nrf52840 on Custom PCBs to create a wireless link from my product to a PC one 840 would be the host and would be wired to the PC using USB (HID,MSC,CDC) and would connect to my Product using an RF link (Gazell) my product would send/receive control data and the host would convert them to the correct USB class messages. the problem: this is my first project using Nordic/keil development so I'm a Nube here. and all Gazell examples only run on the 832 I'm not having any luck converting the projects myself.

I started by using the sdk 13.1.0_7 and the project

Example/proprietary_rf/gzll/Experimental/gzp_desktop pendant

this example uses the 832 and the nrf 51 dongle as the host it seemed like a good starting point but when I changed the project to the 840 in the project settings I get 32 warning all are similar "incompatible redefinition of macro " such as:

C:\Keil_v5\ARM\PACK\NordicSemiconductor\nRF_DeviceFamilyPack\8.12.0\Device\Include\nrf52840_peripherals.h(55): warning:  #47-D: incompatible redefinition of macro "GPIO_COUNT"  (declared at line 55 of "C:\Keil_v5\ARM\PACK\NordicSemiconductor\nRF_DeviceFamilyPack\8.12.0\Device\Include\nrf52832_peripherals.h")
  #define GPIO_COUNT 2

I am wondering is upgrading this is beyond a nube task?

if anybody can help me get a working starting project either by helping me fixing this one or if someone knows of a working Gazell on Nrf52840 Example that I could have.

Thanks

Hi,

You need to do the following changes to get the example to compile:

1. In C/C++ preprocessor symbols:

• Change BOARD_PCA10040 to BOARD_PCA10056.
• Change NRF52832_XXAA to NRF52840_XXAA.
• Remove symbol NRF52 (this symbol will define NRF52832_XXAA for backwards compatibility, creating errors for you).

2. In file nrf_gzp_config.h:

• Change line 149 from #elif defined (NRF52) to #elif defined (NRF52) | defined (NRF52840_XXAA) to make sure GZP_DEVICE_PARAMS_STORAGE_SIZE is defined for nRF52840 as well.

Note that the Gazell examples are not tested on nRF52840, and is not guaranteed to work.

Best regards,

Jørgen

Hi Jorgen, Thanks for the help on this and it is compiling without errors or warnings so I will start testing Thanks again for your help.

Were you able to make Gazell work on nrf52840? For us it compiles fine, but transmission does not work

sorryfor the delay getting back It seemed like the support for Gazell was weak and with me being new to Nordic Development I decided going this way was probably nota good Idea. 

Hope this helps.
