how to get rssi value

woosuk00

hellow.


i have a question.

I'm asking again because I asked the same question last time, but it hasn't been solved.
What I want is if there is anything in TLSR8258 that provides the RSSI value through API functions or variables.

Is there a way to obtain the RSSI value for a received message in the Telink BLE Mesh callback function "void rf_link_data_callback (u8 *p)"?



To estimate the distance between the receiving module and the transmitting modules and identify the closest transmitter,
it is essential to read the RSSI value. Does Telink provide an API function for this?

查找sdk ，寻找类似的函数 blc_ll_getLatestAvgRSSI(void);

There is no such function in the "telink_mesh_sdk".

如果这条消息不会被转发（也就是发送端的ttl设置为0），是可以用说的方法进行距离估测的。

thank you for reply.

I have already checked the documentation and understand what "rssi_pkt" is.
It works fine in "sig_mesh_sdk", but in "telink_mesh_sdk", I get an error stating that the variable is not defined.

Is there no way to use it in telink_mesh_sdk?

Here is the link to the SDK I am using.

telink_mesh_sdk中，变量名是extern u8 light_rcv_rss。和sig_mesh_sdk的不一样;

有点好奇的是：这个rssi 是哪一个节点的rssi? 这个问题搞好几天了。真的是令人沮丧。
