[markevens]

[markevens]

I have made mesh network using esp-idf and want to give ota firmware update to any connected device.

for this i use idea that first root node call https server for get firmware and received packet send to connected node. so that this node store firmware in ota partition and after reboot new firmware start executing.

But for this idea i need way or idea to stream data in mesh network between root to node.

So there is any good way or idea for it ?????????

Hi,
You can initialize one of your devices as BT SPP when it enters update mode lets say when pressing on a button. At that moment connect a smartphone to that device and start streaming your bin file over BT classic. you will need to be receiving the bin file data by CPU0 and writing to OTA partition using CPU1
