How To Create Low Power Temp Sensor nrf51822

[Adi, Robowild]

Hello ,

we are new to BLE

1. We make a long life temp and light sensor , just only transmit from the Nrf to mobile (one way )  , we would like  :

1.1 sensor always be available  for your user phone (can be available every  5 sec if needed),

1.2 automatically connected to  user app 

1.3 running on coin  cell 1 or 2  .

we use s130 ,nrf51822  

1.4 what should be the best method to use , is there any example code link ?

thanks !

1.2) not possible.  Only app can connect to device not the other way around 

See this blog for advertising environment data over BLE works both for nRF51 & nRF52.
