DSPS large current consumption (con't)

Hi MT_dialog,

Actually I have undefined h/w & s/w flow control, and would like to use a GPIO of external MCU to wake up 14580 for data reception and transmission later (rising edge to wake up 14580 and falling edge to let it sleep). All features of 14580 have been implemented but the current consumption is around 1x mA. Would you mind if I send you my whole project's source codes and you help me to take a look? Thanks.

Hi MT_dialog,

In my project, 14580 broadcasts SSID periodically and receives data from external MCU via UART1. Because it always consumes 1x mA current after undefined h/w and s/w flow control (UART TX and RX FIFO should be empty),
1. Can I force 14580 to sleep mode after broadcasting SSID? How to do it?
2. One of GPIO of 14580 is configured as interrupt pin to detect logic high or low, if logic high is detected, 14580 is forced to active forever. If logic low is detected, 14580 is forced to sleep. Is it possible to do it? Should I use app_force_active_mode and app_restore_sleep_mode?
3. If h/w flow control must be defined in order that 14580 can be entered into sleep mode (I think h/w flow control and whether 14580 can be slept shouldn't be related), according to AN-B-026, can I use a "GPIO 1" of external MCU to provide a reset pulse to CTS of 14580 in order to wake up 14580, and use "GPIO 2" of external MCU to detect the lower edge of RTS of 14580 in order to transmit and receive data?

Thanks.

Hi MT_DIALOG,

I will contact your distributer next week but I would like to know why master Mcu can't wake up BLE by RTS if hardware flow control is defined and ext_sleep is enabled. When ext_sleep is disabled, I check CTS interrupt can be triggered and correct data can be received, it seems BLE can't be woke up, please kindly advise.

Hi MT_DIALOG,

You mentioned

1. I found "Enable wake up controller" by EXTERNAL_WAKEUP but do you mean RTS of master Mcu should also connect to another pin of BLE, BLE sleep can be disabled in this gpio interrupt handler and BLE sleep can be enabled somewhere?
2. Futher modification, please provide the example.
Thanks.

Hi MT_dialog,

Refer tohttp://support.dialog-semiconductor.com/dsps-use-gpio-control-its-extend..., I have followed the smart tag reference design in the app_button_press_cb() function, connected RTS of master MCU to P1_0 for external wake up interrupt and reserved P0_2 for CTS of BLE. However, it seemed BLE couldn't be woke up and nothing was printed in app_cts_logi_high_cb(void).

Hi MT_dialog,

1. I'm using basic kit and burning image into EVB by smartsnippets, can I still see the red vertical line if function pxact is called? If so, which layout of smartsnippets should be used such that I can see the red vertical line? If basic kit can't show this line, what can I do to prove the system wakes up?
Also, should I shorten the debouncing time parameter of wkupct_enable_irq() and increase the toggle time of MCU's RTS signal?

2. If wkupct_register_callback and wkupct_enable_irq aren't called, and original api gpio0_callback() of periph_setup.c will be triggered if master MCU toggles its RTS signal, it's quite weird that dialog can receive and transmit data to master MCU. However, if app_timer_set(SPS_TIMER，TASK_APP, 100) is called per 1 second, nothing can be received or transmitted from dialog side. Is it still related to the wakeup issue?

Thanks.

Hi MT_dialog,

Thanks for your help, it's done. But in my source code, I just wonder why I need to add several ms delay in gpio0_callback(), app_cts_logic_high_cb() and app_cts_logic_low_cb() in order that master MCU can transmit and receive UART data from 14580.

Hi MT_dialog,

I would like to know how to turn off radio before app_adv_start and turn on if in need, can I call SetBits16(PMU_CTRL_REG, RADIO_SLEEP) to on and off directly? Thanks.

BR,
