Re: memory usage vs mesh size

I did a little test with low numbers used to set maximum capacity (esp_mesh_set_capacity_num()) and I can join more devices in the mesh than the number I set. If I set my mesh to have max 2 devices, 2 AP connections and 3 layers, I can join 4 devices + the root (total of 5). What is esp_mesh_set_cap...

memory usage vs mesh size

I'm trying to figure out the maximum number of devices that my nodes can support vs the RAM remaining. Changing the mesh max number of devices, number of layers or number of child per node does not have a big impact when no children are connected. Is there information about how much memory is requir...

Re: firmware upgrade encryption using mupgrade

@it_zzc, thank you for the confirmation.
Please also consider providing a way to encrypt all communications, as I realized that this is also an issue with application messages.

firmware upgrade encryption using mupgrade

In ESP-IDF, the the default process for updating firmware rely on TLS to encrypt and hide the firmware update from users (or attackers). When using the mupgrade component, there does not seem to be any encryption other than the WPA password set for the mesh network. A user could then capture the upd...

Re: Flash encryption

Your bootloader is overlapping the partition table. Either reduce the log level for the bootloader or relocate the partition table if your version of IDF allows it.

Re: SPIFFS: how to create more then one partitions?

1) you got it. Just give a different name to your partitions. 2) The name of the partition comes from the partition table. However, the file system prefix (base_path) is not related (see below). 3) you can use different file system prefix for each partition and the prefix can be anything (does not h...
