Re: Is it really necessary to use esp-aws-iot to use aws iot?

Thanks, that's very helpful! I will abandon esp-aws-iot as I can't even subscribe to the device shadow properly and I know it'll take 5 mins in esp-idf.

Is it really necessary to use esp-aws-iot to use aws iot?

I didn't know where else to ask this question so am asking it here. I have been looking at esp-aws-iot to use our product with aws iot and looking at the iot-core-poc example it seems to almost be a completely different sdk, and incredibly verbose and horrible. If we already have firmware written in...

Are you doing cJSON_Delete after creating json structures?

Re: ESP-Mesh vs ESP-Now vs ESP-WiFi-Mesh vs ESP-BLE-Mesh

According to the ESP-WIFI-MESH page, each node in the mesh has ip connectivity: All the nodes in the ESP Mesh network can get IP connectivity and communicate both with each other and the external world. The internet access of these nodes is provided by a root node acting either as a NAT or a bridge....

Re: rtc time doesn't seem to get updated from system time / ntp?

Thanks for the detailed answer, I can probably just use the RTC as sole time source as I don't need the higher precision. I agree there should be a manual way of setting the RTC without going into deep sleep, I might open an issue.

rtc time doesn't seem to get updated from system time / ntp?

I have some devices which were running for several months, and their time was being maintained correctly by sntp. But when I did a soft reboot and just before they got time from ntp, their system time was wrong by a few hours/days. My theory about this, which may be wrong, is that the RTC clock main...

Re: OTA through GSM.

There is no difference between doing it through GSM or wifi or ethernet, any http functions including OTA will just use whatever interface is configured.
You should just have to run esp_https_ota(&config) somewhere in your app and it will work.

Re: Exploring Low Power Mesh Network with ESP-MDF

I have also been thinking about this. I think the answer to your question is probably no - you can configure a device as a sleeping node and send infrequent espnow messages, and you will easily get your required power consumption by doing this, but it expects a non-sleeping router to relay the messa...

Re: (resolved) SNTP sync erratic

I didn't realise you were making a user facing app, in that case it probably makes sense. When I first used sntp I didn't realise it was syncing automatically every hour, I just thought you might have made the same mistake.
