Central multiple characteristics subcribe

[Ars Morozov]

Hello! Is it possible to subcribe on more then one characteristic (which support NOTIFY) on nRF52832 (in Central role)? I check it in nRF Connect app, it's working, so probably peripheral device is ok.

When I subscribe on a few characteristics, only first characteristic value is updating. When I insert delay between first subscribe function and second one, it update only second, etc.

So, what I'm doing wrong?

It is possible. Have you checked that sd_ble_gatts_hvx() returns NRF_SUCCESS on for both characteristics? And that the notifications are actually sent? A sniffer trace may also shed some light on what is going on.
