Hi We have an application where we what to read i2c sensor data over the air to an iPhone. We've taken ble_app_uart_S130 project and grafted in some twi_hardware code. There...
I am interested in the S130 ability to hold 3 central -> peripheral links over BLE, and am looking for some evidence that this has been accomplished with extremely low-power...

Hey guys,
From what I understand, the minimum connection interval on say, an iPhone, is 20ms. Also, you can send up to 6 packets of 20 bytes within a connection interval...
