BLE/BT Power Consumption Test

Introduction:

BLE/BT power consumption test routine (LCPU main frequency at 24MHz). BLE can test broadcast and connection mode power consumption, BT can test Scan and Sniff mode power consumption. The wake-up PIN varies on different development boards, with the following corresponding relationships: - EC-LB58X: Uses PA64 - EH-LB561/EH-LB563: Uses PB34, corresponding to HR_INT on HDK - EH-ss6500/EH-LB523/EH-LB520: Uses PA24, corresponding to GPS_PEN on HDK

When the wake-up PIN is at low level, both HCPU and LCPU cannot enter low power mode. At this time, commands can be sent through HCPU Console to modify parameters. When the wake-up PIN is connected to high level, HCPU can enter low power mode, while LCPU periodically enters and exits low power mode. At this time, Console cannot be used. HCPU uses UART1 as Console port, LCPU uses UART4 as Console port.

Related Console Commands

• HCPU

  1. Factory reset BLE-related Flash data: nvds reset_all 1

     • To avoid Flash conflicts, it is best to execute this command first when using for the first time.

  2. Set Bluetooth MAC address: nvds update addr 6 [addr]. Example: nvds update addr 6 2345670123C3

  3. ‘ble_config adv interval_in_ms’: Modify broadcast period, where ‘interval_in_ms’ is the broadcast interval in milliseconds

  4. ‘ble_config conn interval_in_ms’: Modify connection period, where ‘interval_in_ms’ is the connection interval in milliseconds, command needs to be sent after connecting with phone

  5. ‘btskey’: BTS menu control command, can modify BT parameters. After startup, it defaults to BTS main menu. BTS menu is a multi-level menu. You can send ‘btskey s’ command to display current menu content, then send commands according to menu prompts to enter next level menu or execute certain menu functions. For example, in the main menu, sending the following three commands in sequence can turn on Page Scan and turn off Inquiry Scan

     1. btskey 1

     2. btskey 7

     3. btskey 2

Main menu is shown below

Mobile Phone Recommendations:

1. For iPhone, third-party software LightBlue is recommended; for Android, use nRF Connect for BLE testing.

Project Description

• Supported development boards include

  • ec-lb583

  • ec-lb587

  • eh-lb561

  • eh-lb563

  • eh-lb523

• Compilation method: Enter the hcpu directory and execute the command scons --board=<board_name> -j8, where board_name is the board name. For example, to compile eh-lb561 board, the complete command is scons --board=eh-lb561 -j8 The compiled image files are stored in the build_<board_name> directory of HCPU. For project usage, refer to <> For development boards using NAND, such as ec-lb583, ec-lb587 and eh-lb563, when using the development board for the first time, you also need to execute download_fs.bat in the HCPU project development board directory to flash the file system image to Flash, otherwise it will prompt file system mount failure after startup. The file system image only needs to be flashed once. If the file system is re-flashed, the Bluetooth address will also be lost and needs to be reconfigured.
