How to use Gazelle on NRF51422?

[Adam Czezowski]

Hi,

how do I evoke Gazelle on NRF51422? According to specs NRF51422 supports both ANT and Gazelle although on SDK for 51422 the gzll folder is missing. It is present though in SDK for 51822. I have tried use gzill_ack_payload example from 51822 on my 51422 but got Error: Flash Download failed - "Cortex-m0".

• Does NRF51422 has Gazelle protocol build in?
• If so what needs to be changed in order to use for example gzll_host_ack_payload example present in 51822 SDK on 51422? It this a ROM issue?

The end goal: My sensor network is based on NRF24LE01 and I would like that my new and far more capable NRF51422 will talk Gazelle?

Any pointer will be appreciated.

Regards

Adam

Well self-service! I had to change ROM and RAM addresses according to Soft Device specs and bingo I could program nrf51422 with Gazelle related examples. Now the question remains will it work?

Great that you found the solution! There should be no problems with this, the only reason it isn't included in the SDK is that it isn't currently part of what is being tested before release. Feel free to accept your own answer! :-)
