observer DFU problem

[frogofmagic]

Hello, I'm using this code(observer): github.com/.../nRF51-multi-role-conn-observer-advertiser SDK9.0.0

I try to add DFU function, now can enter dfu mode and iPhone6 can see advertising and connect it. But the connection is very slow and nRF Toolbox will stop at 1%.

If I skip btle_err_code = btle_scan_param_set(scan_param); The update will be fine. I tried init again or call btle_scan_param_set with different parameter, nothing work.

Do anyone know how to fix it?

Sincerely, Kirby

I got answer from my page~

1. Use NVIC_SystemReset() instead bootloader_util_app_start().

2. Modify bootloader 


static void ble_stack_init(bool init_softdevice)
{
    uint32_t         err_code;
    sd_mbr_command_t com = {SD_MBR_COMMAND_INIT_SD, };
    nrf_clock_lf_cfg_t clock_lf_cfg = NRF_CLOCK_LFCLKSRC;
    //if (init_softdevice) // Softdevice must be invoked after system reset
    //{
        err_code = sd_mbr_command(&com);
        APP_ERROR_CHECK(err_code);
    //}
