Issue triggering event when receiving BLE data

Alright, after a couple beers worth of reading through the tutorial several times I found the couple small omissions I had, and all seems to be working. Thanks for pointing me in the right direction!

Yeah, I had all those. The tutorial looks good, I didn't have the forward deceleration of my custom type above the OBSERVER stuff... it seems to be getting farther now. The thing is, blinky has this below the OBSERVER so I'm not sure how that works.

Hi,

Are you getting any events at all in ble_ctcws_on_ble_evt() ? If you place a breakpoint at the function entry, do you hit the breakpoint? Did you register the function with NRF_SDH_BLE_OBSERVER() ?

Something like this ?

#define BLE_CTCWS_DEF(_name)                                                                          \
static ble_ctcws_t _name;                                                                             \
NRF_SDH_BLE_OBSERVER(_name ## _obs,                                                                 \
                     BLE_CTCWS_BLE_OBSERVER_PRIO,                                                     \
                     ble_ctcws_on_ble_evt, &_name)

where BLE_CTCWS_BLE_OBSERVER_PRIO is e.g. 2

And then in main.c, you have something like this:

BLE_CTCWS_DEF(m_ctcws);    /**< My Service instance. */

I would recommend that you take a look at this tutorial on how to create custom services.
