[Anonymous]

Hello,

has someone any problem with the hello_sensor apps?

Sometime i've a problem with this apps. Sometime works this apps pretty well.

after it shows "ecm evt handler: ", then the BCM92073X_LE_KIT is not working well ("read" and "write" function are not working anymore).

The trace shows startup and does not show any connection events.  For the first 30 seconds after startup application performs high duty advertisements sending advertisements every 32 slots (20 msec).  After 30 seconds (I believe this is where you see the trace) advertisements are changed to low duty cycle (interval 1024 slots = 640 msec).  Client still can connect, but to reliably see the advertisements it needs to listen (scan) much more.

The advertisement parameters are configured in hello_sensor_cfg.  Please note that decreasing advertisement interval or increasing duration that device performs high duty advertisements directly affects the battery life of your device.

Ok, maybe that's the problem, why i sometimes can't connect to the BCM92073X_LE_KIT.

Is that right, that my client is the BCM_92073X_LE_KIT? or maybe the Handphone?

How is it actually, sometimes i can't send any data to the client?

I press the "Write" button on the LE Hello Client, but the data doesn't come to the Client (BCM92073X_LE_KIT just ignore it).

I am sorry, I do not understand the question.  How we test this application is we load hello_sensor on one 20737 board and hello_client on another 20737 board.  Connect from iOS LightBlue to the board with hello_client.app.  Push the and hold for 6 seconds application button on the hello_client.  That should establish connection to hello_sensor.  Now if you momentarily push button on hello_client or hello_sensor the message will go to iOS.
