How to persistently store the device name?

[btsjuice]

When the device powers up I want to grab the device name from a known location and also rewrite that same location when I get a new device name. How can I write to the internal flash in the least disruptive way to normal operation? Do I need to use the pstorage.c or device_manager_peripheral.c? The device manager seems to already perform the initialization of pstorage.

void update_name(const char* name) {
  uint32_t err_code;
  ble_gap_conn_sec_mode_t sec_mode;

  // Write the new name to the soft device
  BLE_GAP_CONN_SEC_MODE_SET_OPEN(&sec_mode);
  err_code = sd_ble_gap_device_name_set(&sec_mode, (const uint8_t *)new_name, strlen(new_name));
  APP_ERROR_CHECK(err_code);

  // Write the new name to internal flash
  ????
}

soft device version: 8.0.0

Hi,

You can use pstorage for your application as well as for device manager. There is some example code in the documentation for pstorage (Persistent Storage Manager).

A short example is also included in the answer to this devzone question, including mention of requirements related to block size. For a full example using pstorage (although for SDK 8), see the answer to this question: How can I write 10kB of data to internal flash?
