CC2340R5: How to configure test mode via Bluetooth command configuration？

Alon Chen
Intellectual 405 points
Part Number: CC2340R5

Tool/software:

Dears,

  • 1. When the customer CC2340R5 is in mass production, it needs to test the BLE physical layer parameters. Is there any way to let BLE enter different test modes through Bluetooth wireless signaling, such as
    a) Emission test: power, modulation, frequency, spectrum;
    b) Reception test: bit error rate, receiving sensitivity...
  • 2.It is mentioned in the application note   that UART can be used The test command is configured, but the customer UART is occupied. The customer wants to use Bluetooth commands to configure the test options. Does your company's Bluetooth protocol stack have a method that can be configured in this way, such as the Bluetooth version of the HCI command

Thanks.

    Hello Alon,

    I would suggest to take a look at the following User's Guide section: Production Test Mode (PTM). The PTM allows a BLE application in a "single-chip" configuration to temporarily expose the host control interface (HCI) test commands over the serial interface when triggered externally to do so (e.g. holding a GPIO pin low during power up). This test mode allows the device to be connected to a Bluetooth RF 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.

    In addition, you can take a look at our out of the box example located inside the SDK: "<SDK>\rtos\LP_EM_CC2340R53\ble5stack\basic_ble_ptm"

    BR,

    David.
