details about BLE Stack 1.2 Released:
http://e2e.ti.com/support/low_power_rf/f/538/t/166931.aspx
The article referred:
- Support for "Production Test Mode" has been added, allowing a BLE application in a "single-chip" configuration to temporarily expose the HCI over the UART interface when triggered externally to do so (e.g. hold a GPIO pin low during power up). This allows the device to be connected to a Bluetooth tester in order to run direct test mode (DTM) commands on a production line using the final release firmware, while leaving the UART GPIO pins available for the application to use at all other times
1) Which pins(CC2541) shoulod be used as UART in DTM? Or which pins you will recommend to be used as UART in DTM?
2) "(e.g. hold a GPIO pin low during power up). " Which GPIO pin should be used?
Thanks.
