Private Bluetooth Address

Question

Hello All, 
 i have a problem when I try to change the Bluetooth Address. 
 This is the code that works correctly: err = bt_addr_le_from_str ( "DE:8B:49:00:00:01" , "random" , & addr ); 
 This is the code that NOT works correctly: err = bt_addr_le_from_str("43:8B:49:00:00:01", "random", &addr); 
 If I change "DE" of the Bluetooth Address with some other string like "43" I get the following error: Only static random identity address supported Creating new ID failed (err -22) 
 What could be? How can i fix this? 
 Second questions: We buyed a range of Bluetooth Address but for Classic Bluetooth, can we use this range or we have to buy a specific address for BLE? 
 thanks to everything for the reply Best regards

Hello Einar, 
 before of all thanks for your reply. 
 I have already tried to put "public" and also "public-id" in the call bt_addr_le_from_str() but the result is the same. I still having the following error: Only static random identity address supported Creating new ID failed (err -22) 
 Do you have other suggestions? 
 For point number 2 i'ts ok. 
 Thank you again for your time. Best regards

Hi, 
 To set a public address you need to use bt_ctlr_set_public_addr() . Then you also need " #include <bluetooth/controller.h>". 
 A generic set address wrapper function could look like this: 
 static void set_bt_addr(const char *addr_str, const char *type_str)
{
	int err;
	bt_addr_le_t addr;

	err = bt_addr_le_from_str(addr_str, type_str, &addr);
	if (err) {
 printk("Invalid BT address (err %d)
", err);
	}

	if (addr.type == BT_ADDR_LE_PUBLIC) {
 bt_ctlr_set_public_addr(addr.a.val);
 return;
	} else {
 err = bt_id_create(&addr, NULL);
 if (err < 0) {
 printk("Creating new ID failed (err %d)
", err);
 }
	}
} 
 And be called like this: set_bt_addr("DE:AD:BE:AF:BA:11", "public");
