telink_zigbee_ble_concurrent_sdk-2.4.1.0 issue

wes58

I am trying to convert my old project (Zigbee cooridnator) from TLSR8258 to TL7218 and I can't understand why it is so hard to do. Here are some of the issues I found: #1 Creating new project. To create new project configuration you choose option to copy settings from existing configuration - like in all previous SDK's To exclude this existing app from build of the new project app you go to Resource Configurations->Exclude From Build and select this app. It used to work with all previous SDKs. But now when you compile new app it is still looking for the app that was used when creating new configuration. Now, I had to go through all the settings and look what was causing the problem #2 In the sampleGateway app there are files sampleGatewayMultiBLEController.c and sampleGatewayMultiBLE.c. When I create new project app based on this example, and I have both files in my new app the project doesn't compile because there is nothing that decides which file should be used and it is using both files. I had to delete one of the files for the project to compile. I am not sure how it works with SampleGateway example! #3 Other issues related to the conversion of the TLSR8258 project files to TL7218 due to the functions and other const. that were changed/removed in TL7218 API In TLSR8258 project I used the following function to check link state: `if(blc_ll_getCurrentState() == BLS_LINK_STATE_ADV) {}` And of course this function and enumeration of link state don't exist in TL7218 API. After searching through header files I found function blc_ll_getBleCurrentState() and I use it like this: `if(blc_ll_getBleCurrentState() == BLE_STATUS_ADVERTISING){}` Could you please confirm that it is the correct function? Second issue. In TLSR8258 I used the following function: `bls_att_pushNotifyData(RxTx_CMD_OUT_DP_H, txBuf, p - txBuf);` What is the equivalent function to use in TL7218 API? I would appreciate your help. <i class="pstatus"> 本帖最后由 wes58 于 2026-9-7 10:34 编辑 </i><br /> <br />

8258 is the TC32 (Telink Core) platform, and 721x is the RISC-V platform, with significant differences in their compilation environments. My suggestion is to port your 8258 application code to the 721x project.

And I wrote about the issues I encounterd. The issue is not only "...significant differences in their compilation environments." but that someone decided to change function names, remove some functions, enumerations etc. So if you are working on projects using both TLSR8258 and TL7218 you can't just use the same code. What I wrote in my previous post: #3 Other issues related to the conversion of the TLSR8258 project  files to TL7218 due to the functions and other const. that were  changed/removed in TL7218 API In TLSR8258 project I used the following function to check link state: `if(blc_ll_getCurrentState() == BLS_LINK_STATE_ADV) {}` And of course this function and enumeration of link state don't exist in TL7218 API.

After searching through header files I found the function `blc_atts_sendHandleValueNotify(g_bleSlaveConnHandle, RxTx_CMD_OUT_DP_H, txBuf, length);` which I think is the equivalent for TLSR8258 function `bls_att_pushNotifyData(RxTx_CMD_OUT_DP_H, txBuf, length);` After compiling and downloading the firmware to TL7218 I am stuck. It doesn't work and I don't know why. In BDT pressing PC button (that's the only one that is enabled. No PAUSE, STEP or RUN!) I can see the following: `[10:01:03]: Total time: 184 ms ` `pc : 0x041604  j        0x41600        trap_entry+0x5c ` `pc : 0x041602  c.nop ` `pc : 0x041604  j        0x41600        trap_entry+0x5c ` `pc : 0x041600  c.nop ` `pc : 0x041600  c.nop ` `pc : 0x041602  c.nop ` `pc : 0x041604  j        0x41600        trap_entry+0x5c ` `pc : 0x041602  c.nop ` `pc : 0x041602  c.nop ` `pc : 0x041604  j        0x41600        trap_entry+0x5c` How can I find out what is wrong? The function sampleGwSysException(void) is not called.

The BLE in the zigbee_ble_8258 SDK is single-connection, while the 721x supports multiple connections. The file sampleGatewayMultiBLEController.c only supports the BLE controller, whereas sampleGatewayMultiBLE.c supports full functionality. You can distinguish based on compilation. For single-connection BLE interfaces, you can refer to: https://doc.telink-semi.cn/doc/en/software/res/sdk/ble/tc_ble_en/tc_ble_single_connection_en/ For multi-connection BLE SDK interfaces, you can refer to: https://doc.telink-semi.cn/doc/en/software/res/sdk/ble/tl_ble_sdk_multi_connection_en/tl_ble_sdk_multi_connection_en/ The problem you mentioned is an exception. You can check the code in except_handler and look up RISC-V exception handling online.

You can verify with our original demo; turning this macro(`FLASH_PROTECT_ENABLE`) on and off works fine. One thing to note: the 721x supports interrupt nesting. The RF and systimer interrupts are high-priority. If you change anything in these two interrupts, you need to put the entire interrupt callback function in RAM code, and you’re not allowed to access flash in the interrupt callback, otherwise it could cause flash operation conflicts and exceptions. Maybe check if this is causing the issue? For more details, refer to: https://doc.telink-semi.cn/doc/en/software/res/sdk/ble/tl\_ble\_sdk\_multi\_connection\_en/tl\_ble\_sdk\_multi\_connection\_en/#interrupt-nesting

Thank you for your response. My code is based on sampleGateway with some modification based on my previous TLSR8258 cooridnator project. I didn't add or modify any interrupts. I just tried original sampleGateway project from the SDK. When I change FLASH_PROTECT_ENABLE to 0 there is the same exception that I have. So no, the project that comes with SDK doesn't work either. So for me there is no way to debug and check what is going on. I just left it set to 1.

TL_HUANLI

Yesterday I already pulled the code from GitHub and only changed the FLASH\_PROTECT\_ENABLE macro. I've checked and it works fine. Could you please confirm again? Make sure to clean before compiling the code. Confirm that the configuration matches the hardware. If there are still issues, please let me know the changes and testing methods in detail.

I found that the line that I added before `blc_smp_smpParamInit();` is causing an exception: `blc_smp_setSecurityParameters(Bondable_Mode, 1, LE_Secure_Connection, 0, 0, IO_CAPABILITY_DISPLAY_ONLY);` You wrote before that I can check the code in except_handler but in your example you have the following function to show whether excetpion occurred: ``` static void sampleGwSysException(void) { #if 0         SYSTEM_RESET(); #else         gpio_toggle(LED_POWER);         while(1); #endif } static void sampleGwSysException(void) { #if 0 SYSTEM_RESET(); #else gpio_toggle(LED_POWER); while(1); #endif } ``` So why LED_POWER doesn't turn on when exception occurred? #2 I have another problem with the code ported from my old TLSR8258 project to TL7218. I have a function int RxTxWrite(void * p) where I receive data sent from my phone via BLE. It has been working fine on TLSR8258 for many years but it doesn't work with TL7218. I send for example the following command to get all joined nodes `5500400000` The data received in RxTxWrite function is wrong and is the same no matter what data I send from the phone > [13:00:04]: > TC32 EVK: Swire ok > 255 byte(s) have finished > 00050364: 37 23 4e 0e 13 03 03 c0 23 a0 62 00 b7 02 14 80 > 00050374: 93 82 22 16 05 43 23 80 62 00 97 b1 00 00 93 81 > 00050384: c1 e2 b7 02 10 80 93 82 02 70 01 43 a3 80 62 50 > 00050394: 97 02 04 00 93 82 62 f8 16 81 8b 12 cd ff 82 92 > 000503a4: 8b 12 1d 98 82 92 99 62 f3 a2 02 30 73 10 30 00 > 000503b4: 8b 92 0f d7 73 90 52 30 73 60 01 7d b7 02 00 c4 > 000503c4: 09 43 23 a0 62 00 f3 22 a0 7c 93 e2 12 00 93 e2 > 000503d4: 22 00 73 90 a2 7c 0f 10 00 00 b7 f2 ff a3 93 82 > 000503e4: 02 79 39 43 23 86 62 78 b7 f2 ff a3 93 82 02 79 > 000503f4: 83 83 82 79 13 0e 00 08 e3 08 7e fe b7 f2 ff a3 > 00050404: 93 82 02 79 19 43 23 86 62 78 81 43 23 8e 72 76 > 00050414: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 > 00050424: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 > 00050434: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 > 00050444: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 > 00050454: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 b0 > [13:00:04]: Total time: 185 ms Variable MyRxTxData (in BDT) has nothing in it as well.
