Hi,
I'm using the nRF5_sdk V11.0 and S130 on nRF51822, we need to write a 6 bytes address to the CUSTOMER register(address is 0x100010f8) of the UICR when mass production, then I will read it out to use sd_ble_gap_address_set function change the gap address. The code as follow:
static void Mac_Addr_Set(void)
{
uint8_t i = 0;
uint8_t mac_addr[8];
uint32_t err_code;
ble_gap_addr_t gap_addr;
const uint8_t *addr = (uint8_t *)0x100010f8;
for(i=0;i<8;i++)
{
mac_addr[i] = (uint8_t)*(addr);
addr++;
}
if(((mac_addr[0]!=0)&&(mac_addr[1]!=0)&&(mac_addr[2]!=0)&&(mac_addr[3]!=0)&&(mac_addr[4]!=0)&&(mac_addr[5]!=0))||
((mac_addr[0]!=0xFF)&&(mac_addr[1]!=0xFF)&&(mac_addr[2]!=0xFF)&&(mac_addr[3]!=0xFF)&&(mac_addr[4]!=0xFF)&&(mac_addr[5]!=0xFF)))
{
gap_addr.addr_type = BLE_GAP_ADDR_TYPE_PUBLIC;
memcpy(gap_addr.addr, mac_addr, 6);
err_code = sd_ble_gap_address_set(BLE_GAP_ADDR_CYCLE_MODE_NONE, &gap_addr);
APP_ERROR_CHECK(err_code);
}
But I found that, OTA fails if I read the address out to set the public address，the APP stops at "Enabling DFU bootloader...". OTA is good if I don't call the Mac_Addr_Set() function to set gap address. what is more strange, when the OTA fail, I do OTA again and then is OK. Than is to say, I need to do twice OTA so that it can update the firmware.
Also I use the heart rate example(s130_with_dfu) to test, it meets the same problem. Could anyone give me some advice? Thanks.
Best regards, Alice
