【已解决】紧急求助!蓝牙gatt_server_service_table例程存在问题

Postby linshc » Fri Aug 18, 2023 8:42 am

环境:使用的IDF为ESP-IDF V5.1,开发板为ESP32s3。
问题描述:在使用蓝牙的gatt_server_service_table例程,当创建的GATT Server数超过6个之后(menuconfig中设定了CONFIG_BT_GATT_MAX_SR_PROFILES为11),ble就没有启动服务,也没有启动广播,接着就发生了任务看门狗超时。
当GATT Server的数量小于等于6时,程序正常运行。
问题:
1.上述的问题,我在使用IDF-4.4.4的时候,没有出现这个问题。更新到IDF-5.1后,出现了该问题,本来是在自己工程发现的,后来为了验证,跑了示例工程,然后添加了多个server。
2.从日志看,是否是蓝牙中BTU_TASK任务死掉了,导致触发了任务看门狗。如果是,那是什么原因导致他死掉了呢?
3.我已经修改了CONFIG_BT_GATT_MAX_SR_PROFILES,是否底层没有将这个作为判断依据。依然默认只能创建6个+2个BLE预先使用的server呢?
4.附件是我测试的demo例程,可以下载进行测试。因为是测试demo,所以里面有些乱,但能进行测试,请包涵。

发生错误的日志如下:

希望乐鑫官方工程师,进行下实验,看是否会出现相同的问题?

之前给的工程中,少了nghttp的外部组件,是因为我把他放到了IDF的组件中了,所以编译能通过。现在我把他放到工程中了,我重新上传了工程,以及log文件。

我们已经找到了问题的原因,你可以使用我提供的 patch 来修复该问题,也可以自己进行修改:
找到 esp-idf/components/bt/host/bluedroid/stack/smp/smp_cmac.c 中
static BOOLEAN cmac_aes_k_calculate(BT_OCTET16 key, UINT8 *p_signature, UINT16 tlen) 函数


修改:
UINT8 i = 1, err = 0;

UINT16 i = 1, err = 0;

再次感谢你报告的问题,后面我们会将更新同步到最新的 IDF。
