Hi ,

i have test the glucose demo with Android app(like nrf conenct), it works fine.

but with the wireless uart demo, the connection will immediately terminated when the connection established. 

when using the iphone, the log from lightblue shows the service are all discovered. the disconnect request is send by the kw36. 

 

here is the log from kw36 uart:

----------------------------------------------------------------------------------- serial port log -----------------------------------------

Wireless UART starting as GAP Central, press the role switch to change it.

Switched role to GAP Peripheral.

attention: i have tested 5 times, as log shows

 

so the problem is absolutely connection issue, not the state/button setting of the kw36. 

i have a TI sniffer log, but it seems no use。
