23K + messages
2020-06-17 02:55:14 +00:00
+ heap of 70ish packets, 300ish bytes per packet: 20KB
2020-06-16 22:01:39 +00:00
+ 14KB soft device RAM
2020-06-17 02:55:14 +00:00
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)
2020-06-16 22:26:30 +00:00
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
2020-06-17 02:55:14 +00:00
d) a smarter MeshPacket in memory representation would save about 7KB of RAM. call pb_release before freeing each freshly malloced MeshPacket
