2 Hardware BOM and Firmware Modification

In order to reduce leakage current as much as possible, there are some necessary changes to implement.

  • Hardware bill of material (BOM) changes
Table 2-1 Table 1. BOM Changing of TIDA-010224
Change Position Note
Delete CC1352 EVM board In these test cases, no Sub-1 GHz connection.
Delete R116, R137, R91, R152, R118, R35-R40, R127, R128
Change Net float U4.5 pin
Change Net Exchange resistor on R159 and R160 position Make CC3235 can control
  • Firmware changes

Add Function Detail
Hibernate mode
  • Enter Hibernate mode via UART input '1'.
  • Choose which audio from, no audio/from microphone/from ring music after RTSP connected.
  • Be wakeup by any of UART input.
  • If there is not a saved AP list in site, enter provisioning mode after it is in wakeup.
  • If there is a saved AP, connect with AP and prepare accepting RTSP connection after wakeup.
Intermittently Connected mode
  • Enter Intermittently mode via UART input '2'.
  • Choose which audio from, no audio/from microphone/from ring music after RTSP connected.
  • Define remote TCP server IP address.
  • Define interval wakeup time from hibernate.
  • Output 100 data to remote TCP server after wakeup.
  • Wakeup by any UART input when it is in hibernate.
  • Enter accepting RTSP connection mode after wakeup by GPIO (UART input)
Always Connected with Long Sleep mode/with IOT mode
  • Enter always connected mode via UART input '3' or ‘4’.
  • Define beacon time of connecting with AP.
  • Choose which audio from, no audio/from microphone/from ring music after RTSP connected.
  • Define remote TCP server IP address.
  • Define interval time of sending data to TCP server.
  • Send out 100 data to remote TCP server after wakeup from LPDS mode by RTC.

  • Wakeup by any UART input when it is in LPDS.

  • Enter accepting RTSP connection mode after wakeup by GPIO (UART input).
Measure Time of Key action mode
  • Enter measure time mode via UART input '5’.
  • Define remote TCP server IP address.
  • Send 10 pages image data to TCP server after triggered by any UART input.
  • Print timestamp of key action, same time, output HW signal via CC3235 GPIO_06 pin.
