Hi,
I know that this question has been asked before but I was wondering if someone can help me understand if the problem is from the connections on my board or my chip...
I am developing a fairly complex app which involved having a lot of logging using the NRF_LOG macros with the UART backend. I am using the nRF52 DK as my platform with nRF...
My app is based on ble_app_hrs_rscs_relay, i.e. the nRF52 DK is acting as central and peripheral at the same time.
SDK 17.0.2, SD S132 v7.
I have a service running there...
Hello, Can your tell me is it possible make three from one device at the same time ? If is not, can I make multiple connection with profiles which support multiple connection...
My goal is to synchronize the clocks of several nodes in a mesh network. I would like the client node to distribute the current time to all the server nodes in the network...
