Zigbee BLE Concurrent - BLE issue

wes58

I am trying to build SampleGW app with added BLE security.
I added the following in user_ble_init(void){}

blc_smp_setSecurityLevel(LE_Security_Mode_1_Level_4);

            blc_smp_setSecurityParameters(Bondable_Mode, 1, LE_Secure_Connection, 0, 0, IO_CAPABILITY_DISPLAY_ONLY);

            blc_smp_setDefaultPinCode(123456);

After trying to build I get the following error:

<artificial>.text.blt_smp_sc_handler+0xaec): undefined reference to `eccp_pointVerify'
/cygdrive/c/TelinkIoTStudio/RDS/V5.3.x/toolchains/nds32le-elf-mculib-v5f/bin/../lib/gcc/riscv32-elf/12.2.0/../../../../riscv32-elf/bin/ld.bfd: //cygdrive/c/Users/Wieslaw/AppData/Local/Temp/cc8tFlku.ltrans5.ltrans.o: in function `.L1438':

<artificial>.text.blt_ecc_gen_key_pair.constprop.0+0xd8): undefined reference to `eccp_pointMul'
collect2: error: ld returned 1 exit status

Compilation fails on this function: blc_smp_setSecurityParameters(Bondable_Mode, 1, LE_Secure_Connection, 0, 0, IO_CAPABILITY_DISPLAY_ONLY);

What is wrong? When I try to compile BLE part in just BLE SDK there is no problem.

The tl721x driver library is missing some files, please try and use this new driver library file.

Thank you very much for your help. It worked.

By the way, I noticed that your website misses English translation. For example It has 回复 instead of REPLY... etc.

The other thing I noticed on your Github https://github.com/telink-semi/telink_zigbee_sdk/tree/master Zigbee SDK shows as upgraded to version 4.0.1.0 but it is not Zigbee SDK. If you look in PLATFORM folder it doesn't have all the chips that Zigbee SDK supported. In the STACK folder there are folders like ble, ieee802154, zigbee, zigbee_direct. TL7218 supports Zigbee Direct so why isn't it in the platform folder?
Is there a Zigbee Direct SDK on the GitHub that supports TL7218?

Thanks for your feedback. The v4.x is an all-in-one SDK, and tl721x might be added in the next version.
