To the kind attention of Nordic support team,
We are going to use gazell protocol for some of our wireless products. Could you please point me out to the relevant documentation about how gazell protocol machine gets its time base? Do you recommend the usage of the XL1, XL2 sub oscillator for more precision? I have to say that our device is not going to have power problems, so will it suffice to have the main oscillator and trigger any sort of software correction? In this case is there some change that must be done to the code in order to inform the gazll stack about the timing source?
I believe you should be able to find answers to your questions in the documentation:https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v15.3.0/gzll_02_user_guide.html?cp=5_1_5_3
There is no exact answer here, but the Gazell protocol will be able to maintain synchronization for 50-100ms.
Thank you very much for replying us. As your documentation states gzll_arm.lib needs NRF_TIMER2 and gzll_sd_resources_arm.lib needs NRF_TIMER0. I think it may infer that the main oscillator should be fine, as the timing source. Anyway, we could have an idea about the overall transmission efficiency in an empirical way, letting two device transmit and receive for a long time and monitoring how many failures, if any. So that we could also tune gzll radio parameters in a pratical way. Is there anything else, or a laboratory mean, that you could also recommend in order to investigate the real effect of gazell radio parameters on the overal communication efficiency? Thank for your kindness
Thank you very much for your advises. They are really helpful. The second one and the third are clear, we understand how to put them into practice. May you please explain a little bit further the first one, please? We are going to use multiple devices and a gazell host. So it should be nice to better comprehend your meaning. It is clear that we want to theoretically avoid congestion as much as it is possible. May you please argument with a little practical example what is the gazell parameter that is key in this aspect? Thanks in advance
Thank you for everything. Very clear
