Dude, thank you so much for your two videos introducing ESP32C6 TWT low power consumption. I've also been using battery power recently and periodically transmitting small amounts of data to a server on the local network. I found that using 802.11 tx is more energy-efficient compared to UDP (like socket) or TCP (like MQTT). If the network signal is good, then I think iTWT+802.11 with simple application layer retransmission might be the best approach in scenarios with small periodic data transmission. What do you think?
Hi @mintisan, great that the videos are helpful for you. Based on my measurements iTWT should be a very good option for battery operated devices that only send small data. I like the fact that I would not need a gateway like with ESP-NOW and can use my WiFi infrastructure as is. However that is also where I have the biggest issues. Right now I dont have a router or AP that supports iTWT for sleep periods that I would like.
@@TheEmbeddedDude Yes, the need for an additional ESP-NOW GW increases the cost and maintenance of product deployment. Regarding iTWT, I purchased the AX56U mentioned earlier and am experimenting with different cycle settings. If there is any progress, I'll reply here as a reference for you [though I've been quite busy with work projects lately, so it might take some time]. I just want to find out and verify if iTWT+802.11 is the best way for periodic small amounts of sensor data.
