Scale up 802.15.4 network

nick002025 — Tue, 17 Apr 2018 18:46:05 GMT

I am trying to scale up my 802.15.4 network to handle more end devices in the coordinator. When a batch of end devices is trying to communicate I am seeing gMcpsDataCnf_c status return 0xF1 = gTransactionOverflow_c.

I am guessing based on the comments that this means the buffer is full in the mac library. How can I increase the buffer size?

Hello,

Sorry for the inconvenience this might cause you, but the library definitions and functions in the library can't be modified as those are not public.

Regards,

All of the messages are using dynamically allocate buffers. To scale up, would it be simple as increasing the number of memory pools available in MemManager.h?

#define PoolsDetails_c \

blocksize_ 64 numberof_blocks_ 8 poolid_(0) eol \

blocksize_ 128 numberof_blocks_ 2 poolid_(0) eol \

blocksize_ 256 numberof_blocks_ 6 poolid_(0) eol

#endif
