There was a problem hiding this comment.
Provided some comments inline.
In general, would it be desired to keep this functionality out of a Thread 1.1 build and a 1.2 build? Since it's 1.3 functionality. If we include it in 1.1 builds then I wonder what the exact meaning of the "1.1" build flag has become.
include/openthread/mesh_diag.h

| int8_t mAverageRssi; ///< Average RSSI. | ||
| int8_t mLastRssi; ///< RSSI of last received frame. | ||
| uint16_t mFrameErrorRate; ///< Frame error rate (0xffff->100%). Zero if not known or supported. |
There was a problem hiding this comment.
It could be clarified that value 0 would also represent an actual error rate of 0, for both fields, in case the error rate tracking functionality is supported. My initial assumption was that 1 would represent a zero error rate because 0 is already taken for "not known or not supported".
Also the type of error is not really clear. This could be clarified maybe in the comment above the typedef since there is more space there. The comment there could, if needed, refer to another file where the type of error is more clearly explained. For example network_diagnostic_tlvs.hpp has an extensive comment for each field of the items we see here, including frame error rate and message error rate.
Type of error could be e.g. Tx failures only, Rx decoding/incomplete/checksum/security errors only, or both Tx/Rx stats combined in a single value.
There was a problem hiding this comment.
Yes. Thanks. I agree Zero if not known can be confusing. I intended it as if you don't support error rate track, set then to zero, but we can use mSupportsErrRate flag to tell if the error rate values are valid, otherwise value should not matter and we should ignore them.
In the next push, I remove this and make it simpler. Also added a comment at the top to explain the error rate a bit more.

This commit contains multiple changes to Network Diagnostics modules. It adds new TLVs: Child TLV, Child IPv6 Address List TLV, Router Neighbor TLV and MLE counters TLV. Child TLV contains information about a child entry including RLOC16, extended MAC address, mode (rx-on-idle, FTD/MTD, full netdata, CSL-sync), timeout, age, supervision interval, CSL period and timeout, and link quality info such as RSS (last and average) and frame/message error rates. Neighbor TLV provides similar info for a router neighbor. The Child IPv6 Address List TLV allows to query a parent to get the list of IPv6 addresses registered by its MTD children. The new Child and Neighbor TLVs can be requested in Network Diagnostic Get Query "d/dq" message to a router (unicast) or multiple routers (multicast). The router responds with one or more Network Diagnostic Get Answer "d/da" messages. We allow multiple Answer messages to be sent in response to a Query. This is to support the case where a router has many children, and we want to avoid sending a large message that contains all of the TLVs for all of the children. Instead, we can send a sequence of Answer messages, each of which contains a subset of the TLVs. Each Answer message includes an Answer TLV that indicates the index of the message in the sequence. The first Answer message has an index of 0, the second has an index of 1, and so on. The Answer TLV also indicates whether the message is the last one in the sequence, or if there are more Answer messages to come. Answer messages are sent in sequence, and the next one is not sent until we receive a successful CoAP ACK/response for the previous one. This commit adds a Query ID TLV (with a 16-bit identifier as it value) that can be optionally included in a Query message. The Query ID is echoed back in all Answer messages associated with the same Query message. This allows a node that sends multiple Queries to distinguish between the received Answers. This commit updates `MeshDiag` to use the newly added TLVs to query the child table or children IPv6 addresses of a router. New public OpenThread APIs under `otMeshDiag` are added for this, along with CLI commands and their documentation. A test-case is added to validate the newly added mechanism.

This commit contains multiple changes to Network Diagnostics modules.
It adds three new TLVs: Child TLV, Child IPv6 Address List TLV, and Neighbor TLV. Child TLV contains information about a child entry including RLOC16, extended MAC address, mode (rx-on-idle, FTD/MTD, full netdata, CSL-sync), timeout, age, supervision interval, CSL period and timeout, and link quality info such as RSS (last and average) and frame/message error rates. Neighbor TLV provides similar info for a router neighbor. The Child IPv6 Address List TLV allows to query a parent to get the list of IPv6 addresses registered by its MTD children.
The new TLVs can be requested in Network Diagnostic Get Query "d/dq" message to a router (unicast) or multiple routers (multicast). The router responds with one or more Network Diagnostic Get Answer "d/da" messages.
We allow multiple Answer messages to be sent in response to a Query. This is to support the case where a router has many children, and we want to avoid sending a large message that contains all of the TLVs for all of the children. Instead, we can send a sequence of Answer messages, each of which contains a subset of the TLVs.
Each Answer message includes an Answer TLV that indicates the index of the message in the sequence. The first Answer message has an index of 0, the second has an index of 1, and so on. The Answer TLV also indicates whether the message is the last one in the sequence, or if there are more Answer messages to come. Answer messages are sent in sequence, and the next one is not sent until we receive a successful CoAP ACK/response for the previous one.
This commit adds a Query ID TLV (with a 16-bit identifier as it value) that can be optionally included in a Query message. The Query ID is echoed back in all Answer messages associated with the same Query message. This allows a node that sends multiple Queries to distinguish between the received Answers.
This commit updates
MeshDiagto use the newly added TLVs to query the child table or children IPv6 addresses of a router. New public OpenThread APIs underotMeshDiagare added for this, along with CLI commands and their documentation. A test-case is added to validate the newly added mechanism.Related to SPEC-1151 and SPEC-1150.
