NRF51822 BLE ~400uA idle current consumption #24564

Closed scttnlsn closed 4 years ago

scttnlsn commented 4 years ago

I'm trying to create a BLE peripheral that periodically notifies the central of a sensor value and then goes to sleep. I'm noticing that even during the k_sleep, there's a significant current draw of ~400uA at 3.3V. Here's the full code of a minimal example that reproduces the issue:

#include <zephyr.h>
#include <device.h>

#include <zephyr/types.h>
#include <stddef.h>
#include <string.h>
#include <errno.h>
#include <sys/byteorder.h>
#include <sys/types.h>

#include <bluetooth/bluetooth.h>
#include <bluetooth/hci.h>
#include <bluetooth/conn.h>
#include <bluetooth/uuid.h>
#include <bluetooth/gatt.h>

static u8_t val = 0;

// 8D9D7800-5B61-412A-AB71-5C7E0E559086
static struct bt_uuid_128 uuid_service = BT_UUID_INIT_128(
  0x86, 0x90, 0x55, 0x0E, 0x7E, 0x5C, 0x71, 0xAB,
  0x2A, 0x41, 0x61, 0x5B, 0x00, 0x78, 0x9D, 0x8D);

// 8D9D7801-5B61-412A-AB71-5C7E0E559086
static struct bt_uuid_128 uuid_characteristic = BT_UUID_INIT_128(
  0x86, 0x90, 0x55, 0x0E, 0x7E, 0x5C, 0x71, 0xAB,
  0x2A, 0x41, 0x61, 0x5B, 0x01, 0x78, 0x9D, 0x8D);

static ssize_t ble_read_value(struct bt_conn *conn, const struct bt_gatt_attr *attr, void *buf, u16_t len, u16_t offset) {
  const uint8_t *value = attr->user_data;
  return bt_gatt_attr_read(conn, attr, buf, len, offset, value, sizeof(*value));
}

static void ble_ccc_cfg_changed(const struct bt_gatt_attr *attr, u16_t value) {
  ARG_UNUSED(attr);

  bool notif_enabled = (value == BT_GATT_CCC_NOTIFY);
  (void) notif_enabled;
}

BT_GATT_SERVICE_DEFINE(ble_gatt_service,
  BT_GATT_PRIMARY_SERVICE(&uuid_service),

  BT_GATT_CHARACTERISTIC(
    &uuid_characteristic.uuid,
    BT_GATT_CHRC_READ | BT_GATT_CHRC_NOTIFY,
    BT_GATT_PERM_READ,
    ble_read_value,
    NULL,
    &val),

  BT_GATT_CCC(ble_ccc_cfg_changed, BT_GATT_PERM_READ | BT_GATT_PERM_WRITE),
);

// advertisement data
static const struct bt_data ad[] = {
  BT_DATA_BYTES(BT_DATA_FLAGS, (BT_LE_AD_GENERAL | BT_LE_AD_NO_BREDR))
};

// scan response data
static const struct bt_data sd[] = {
  BT_DATA(BT_DATA_NAME_COMPLETE, CONFIG_BT_DEVICE_NAME, (sizeof(CONFIG_BT_DEVICE_NAME) - 1)),
};

void ble_ready(int err) {
  if (err) {
    return;
  }

  bt_le_adv_start(BT_LE_ADV_CONN, ad, ARRAY_SIZE(ad), sd, ARRAY_SIZE(sd));
}

void main(void) {
  bt_enable(ble_ready);

  int counter = 0;

  while (1) {
    bt_gatt_notify(NULL, &ble_gatt_service.attrs[1], (u8_t *) &counter, 1);
    counter++;
    k_sleep(3000);
  }
}

Do I need to explicitly force a certain sleep mode? Do I need to explicitly disable certain peripherals?

Thanks!

The normal go-to explanation for idle power draw of this level is a UART left active, but it seems you don't have UART enabled so that wouldn't be the case here. I do wonder about the impact of SEGGER_RTT, might try turning that off.

How are you measuring the power? FWIW my testing long ago showed the base BLE400 current usage was 120 uA, even if the jumpers to connect UART, LED, and buttons were removed, in applications where the underlying nRF51 daughterboard was using only 3.2 uA. It may be that the draw is not due to the nRF51 but rather something else on your board.

scttnlsn commented 4 years ago

@pabigot Thanks for the tips. I tried powering just the daughterboard and that brought the usage down to ~200uA so I must have some leakage somewhere on the motherboard. The SEGGER_RTT value did not seem to have any impact. I'm just using a DMM to measure the current consumption but perhaps it's so low now that I need a proper device to overcome the burden voltage.

pabigot commented 4 years ago

I like the EEVBlog uCurrent for DMM-based measurement, but I don't see where you can buy them anymore.

@scttnlsn Nordic does offer a Power Profiler Kit in case that is of interest: https://www.nordicsemi.com/Software-and-tools/Development-Kits/Power-Profiler-Kit Do you think we should close the issue now?

scttnlsn commented 4 years ago

OK, thanks for the suggestions. Yeah, let's close this for now. I'll put together a better current measuring setup and reopen this if I'm still having issues going forward. Thanks!

hello guys @scttnlsn @carlescufi a quick doubt, I am also using zephyr and i am migrating a project, i wanted to ask you if by using k_sleep might be enough for making the device into deep sleep? specifically i am doing this:

void main(void)
{
    bt_addr_le_t ble_addr = { BT_ADDR_LE_RANDOM, addr };
    bt_id_create(&ble_addr, NULL);
    bt_enable(bt_ready);
    while (1) {
        k_sleep(K_SECONDS(3));
        bt_le_adv_stop();
        k_sleep(K_SECONDS(30));
        bt_le_adv_start(
            BT_LE_ADV_NCONN_IDENTITY, advertisement_payload, 
            ARRAY_SIZE(advertisement_payload),
            NULL,
            0
        );
    }
}

it does work and advertises shortly as i wanted, but i have my doubts, if it is really deep sleep or in my use case can be considered a good option like this, thanx!
