gammu VS esp_lte_modem

2. Using https://smseagle.eu/store/en/devices/28-smseagle-nxs-9700-4g.html. Problem: The product is awful and support is worse. They use https://github.com/gammu/gammu which no longer has a maintainer so they sorta kinda maintain it. I don't have the resources to volunteer to be the maintainer and put it on my own hardware.

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
