LAUNCHXL-CC26X2R1: Finding BLE MAC Address

Device: CC26X2R1 LaunchXL

SDK :simplelink_cc13x2_26x2_sdk_5_20_00_52

Hi TI,

I want to get the BLE MAC Address

I have an old procedure for CC2640R2

GAPRole_GetParameter(GAPROLE_BD_ADDR, u8_macAddress, NULL);

for (uint8_t u8_index = 0; u8_index < B_ADDR_LEN; u8_index++)
{

pu8_macAddr[u8_index] = u8_macAddress[(B_ADDR_LEN - 1) - u8_index];
}

*(pu16_size) = (uint16_t) B_ADDR_LEN;

GAPRole_GetParameter is defined in multi.h in simplelink_cc2640r2_sdk_5_10_00_02 for CC2640R2 but in simplelink_cc13x2_26x2_sdk_5_20_00_52 for CC26x2R1 multi.h is discarded and lot of API's also changed .

I see that in migration of CC2640R2 to CC26X2R1 the API GAPROLE_BD_ADDR is changed to HCI_ReadBDADDRCmd() I see it's working as it is returning only HCI_Success but it not giving any BLE MAC address .

Can you suggest me the method to get the BLE MAC Address (as of I have mentioned for CC2640R2 in green) and the API's exactly related to it in detail please.

Hi Manikanth,

Please refer to the Receiving HCI Events section of the BLE5-Stack User's Guide. Basically, you should be able to process the HCI_READ_BDADDR cmdOpcode inside the HCI_COMMAND_COMPLETE_EVENT_CODE case of [application]_processStackMsg.

Regards,
Ryan

I have gone through those things but couldnot get the right way I have also observed the API changes with respect to GAP GATT etc.

Can you please provide me the code snippet of my requirement to get BLE MAC Address please as I have mentioned like this.

For your reference, I usually use the following codes to read device BLE address.

#include <inc/hw_fcfg1.h>
uint64_t bleAddress;
bleAddress = *((uint64_t *)(FCFG1_BASE + FCFG1_O_MAC_BLE_0)) & 0xFFFFFFFFFFFF;

Hi Manikanth,

Let us know if Yikai's snippet works. If it's still an issue afterwards, we will find a way to help you resolve this promptly.

Best,

Nate

Yeah I'm expecting other way interms of API's w.r.t BLE or HCI.Because from one of your thread I got the same thing which mentioned in YiKai Chen snippet that didnot work quite well for me. So please suggest me a better way.

Thankyou

Can you elaborate what you mean “didnot work quite well for me?”

I didnot find this API FCFG1_BASE any where.I would be pleased if you provide me a way.

FCFG1_BASE is the address of Configuration base. You only need to add "#include <inc/hw_fcfg1.h>" in the beginning of your source file before you can use it.
