examples of simple peripheral/central ble transmission nrf52 series

[loganmeyer3]

I am very familiar with PICs and some atmega stuff, just graduated university ee and the project I am working on requires transmitting very small amounts of data continuously via ble protocol. Actually transmitting real time gyroscope data. Nrf modules seemed the easiest/cheapest for our purpose and decided we would most likely end up going with someones 52 series module. I have been playing around awhile with the nordic 52 development board however I am finding the learning curve fairly steep with zephyr. I can do basic stuff, gpio, pwm, interrupts etc but am struggling with bluetooth. Would it be possible to get an example of a central device and peripheral device with a custom service and characteristic 128, that simply sends or receives 24 or more bits of data at a time.   I'm really trying to learn this and just feel myself lost, thanks.  I have been through many of the peripheral and central zephyr examples.

Thanks Andreas,  I have already gone through that course and have looked at the majority of the examples provided by nrf connect.  I have focused on central and peripheral example and have focused on uart central and peripheral example.  I know I am a slow learner but I have been studying this for 8 hrs a day for the past almost 3 weeks.   I understand the NUS service but I fail to understand how to make a custom service from custom uuid and send individual bytes of data in array format.  I apologize for my ignorance,  I am just greatly struggling.
