Detect when BLE connection is made (Arduino library)

[Mukund]

Hey,

thanks for bringing this up. Currently its just possible to get the current number of connections with:

Code:

uint16_t PhyphoxBLE::currentConnections

Unfortunately there is no way to "auto-start" the experiment or get information about the current state of the play-button right now. But I think this could be added relatively easily. I will talk with one of our student assistant who is already working on some updates for the library to add this feature in near future. 

Cheers

 Hi Dominik, 
 I wanted to ask you if there has been an update on the same feature requested by @heliophagus. 
 My project requires me to send high rates of data(100-120 samples/second) from an Arduino nano 33 BLE and simultaneously store the data in a SD-card   connected with the Arduino. 
 In order to sync the data being displayed in the graph of the phyphox app and the ones I store in the SD-card, it is important for me to know when the "play"   button is pressed in the app. 
 Alternatively, is there a way I can send, say a 5 min data buffer from phyphox to the arduino? I can then store the data buffer directly into the SD card. 

 Regards,
