23K + messages
|
|
+ heap of 70ish packets, 300ish bytes per packet: 20KB
|
|
+ 14KB soft device RAM
|
|
|
|
With max length Data inside the packet
|
|
Size of NodeInfo 104
|
|
Size of SubPacket 272
|
|
Size of MeshPacket 304
|
|
|
|
If Data was smaller: for 70 data packets we would save 7KB. We would need to make SubPacket.data and MeshPacket.encrypted into "type:FT_POINTER" - variably sized mallocs
|
|
Size of NodeInfo 104
|
|
Size of SubPacket 96
|
|
Size of MeshPacket 292 (could have been much smaller but I forgot to shrink MeshPacket.encrypted)
|
|
|
|
therefore:
|
|
a) we should store all ToPhone message queued messages compressed as protobufs (since they will become that anyways)
|
|
b) shrink packet pool size because none of that storage will be used for ToPhone packets
|
|
c) don't allocate any storage in RAM for the tophone messages we save inside device state, instead just use nanopb callbacks to save/load those
|
|
d) a smarter MeshPacket in memory representation would save about 7KB of RAM. call pb_release before freeing each freshly malloced MeshPacket
