基于SerialBLEbridge V1.4.1实现BLE和UART透传功能,修改simpleProfileAttrTbl属性表后通知功能失效
基于SerialBLEbridge V1.4.1实现BLE和UART透传功能,读和写都通实现透传了,但修改simpleProfileAttrTbl属性表,去掉Characteristic 1到Characteristic 3后影响到了Characteristic 4,Characteristic 4的通知功能失效,Characteristic 4的写数据没问题,读数据是在通知是侦听的,通知失效后读数据就失效了。
static gattAttribute_t simpleProfileAttrTbl[] =
{

0, /* handle */

};
请问是哪里出了问题?
去掉Characteristic 5的定义就没影响,去掉Characteristic 4前面的定义就受影响,不知道为何?
论坛有类似问题,参考这边解答: https://e2e.ti.com/support/wireless_connectivity/bluetooth_low_energy/f/538/p/349378/1223423
按以上链接的这个方法不行,我的simpleProfileChar4定义成这样:
static uint8 simpleProfileChar4[SIMPLEPROFILE_CHAR4_LEN] = {0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0};
static uint8 simpleProfileChar4Props = GATT_PROP_NOTIFY|GATT_PROP_READ|GATT_PROP_WRITE|GATT_PROP_WRITE_NO_RSP;
我要通过simpleProfileChar4这个数组实现透传数据的存放,会不会是这个有影响,但是没注解掉属性表中的Characteristic1-3是可以的。
源程序上传,simpleProfileAttrTbl表这样定义就OK,但我只想要Characteristic4,一注解掉Characteristic1-3就造成通知失效,APP写数据到UART是正常的,UART发数据到APP就没有。

尝试直接把在simpleProfileChar1基础上改成simpleProfileChar4 的模式,把simpleProfileChar2-5去掉
是这个地方出了问题:noti.handle ,写死了
