Hello everyone!
I want to use BLE with the filesystem (FS), but I haven’t found any examples. When I enable BLE advertising, any filesystem operations stop working.
(As a base, I used this example: https://github.com/Toastee0/Seeed-Xiao-nRF54L15/tree/main/xiao_expanded/sd_card_hw and added the BLE part in main.)
int main(void)
{
LOG_INF("========================================");
LOG_INF("XIAO nRF54L15 SD Card + ZMS Sample");
LOG_INF("========================================");
int err;
err = bt_enable(NULL);
if (err) {
LOG_ERR("Bluetooth init failed (err %d)", err);
return err;
}
// LOG_INF("Bluetooth initialized");
// 3. Start advertising
err = bt_le_adv_start(&adv_param, ad, ARRAY_SIZE(ad), NULL, 0);
if (err) {
LOG_ERR("Advertising failed to start (err %d)", err);
return err;
}
#ifdef CONFIG_ZMS
/* Initialize ZMS for persistent storage */
LOG_INF("Initializing ZMS...");
int zms_rc = zms_init();
if (zms_rc == 0) {
zms_demo();
} else {
LOG_ERR("ZMS initialization failed, continuing without persistent storage");
}
#endif
/* raw disk i/o */
LOG_INF("Initializing SD card...");

break;

LOG_ERR("Unable to get sector count");

Without BLE advertising, everything works fine, but with it, the system can't mount or open any files, and similar operations fail. Maybe someone can suggest something?
