Save settings

Leon Schmetz

Just wondering,

What if I configure the Tx power level or some other attribute. What do I have to do to save the value to be used when the unit restarts?

    Hi Leon,

    If you have some config settings or variables that are dynamic, you can store these to flash to set these when reset occurs.

    Pseudo:

    if ( *(uint32_t *) CONFIG_ADDRESS != 0xFFFFFFFF) NRF_REGISTER->REG = CONFIG_ADDRESS; else NRF_REGISTER->REG = DEFAULT_VAL;

    The ble_flash library can be used to store to flash. Most BLE-projects use this to store bonding information on disconnect.

    Best regards Håkon
