esp-idf-lib VS esp_lte_modem

External libraries are added as 'components'. I suggest you take a look at the great work by UncleRus et al, you can add the repository as a git submodule and add the items you want to use as a 'REQUIRES' statement in your CMakeLists.txt file.

The library by UncleRus has an example and it mentions you should (and this probably is right).

The library is: https://github.com/UncleRus/esp-idf-lib and the example uses the DHT (Humidity sensor) library.

My first idea to solve this was to create my component which implements a mutex to access each I2C bus. Now, when I was searching github for previous implementations, I saw this repo https://github.com/UncleRus/esp-idf-lib. Not only does it have the solution for I2C it also has components for some of the sensors I am using.

With some research found out the library actually works correctly when run outside of platformio with idf.py as stated here: https://github.com/UncleRus/esp-idf-lib/issues/46

i was trying to use PPPoS with sim7600 and esp32, there is code on github which has esp32 idf pppos support for sim7600, the first time i tried i had not set APN, but the the example got connected to MQTT server and the message was delivered. below is the log for same,

Hi, LoRa has acceptable use which limits it to around 30k/day so not possible. The LTE option is a good idea, check with your mobile signal strength at the desired spot. To get it lasting you could use a rechargeable LiPo battery which should be good for 5000 recharges. A small solar panel will easily keep it topped up, especially if it’s sending one pic/day. You want to find an esp32 LTE board with good sleep stats. These may help https://randomnerdtutorials.com/power-esp32-esp8266-solar-panels-battery-level-monitoring/ with regard to connecting a remote camera, you may find it easier the other way round. Get esp32-cam board, then find a LTE modem. https://github.com/olliiiver/esp_lte_modem
