Hello everyone, I want to make a project with lora modules. I am going to use adxl345 and one lora module. I won't going to charge the battery, microcontroller will work with that battery like 1 year. For now I am thinking of using 3 lora module. One is as a gateway with esp32 and the others will be end node.
I haven't been use any lora project yet and some things confuse me.
When I check to github there are Lora and Lorawan libraries.
If I use lora libraries with esp32 as a gateway, esp32 will communicate with (for example) 100 nodes (point to multipoint), then esp32 will send this end node values to the internet (with http client). It will became a Lorawan right ?
So as I say, there are Lora and Lorawan libraries, I think both using lora protocol. So is there any power consumption difference?
I know I asked a lot but last question, I am going to send sensor values to the gateway. End nodes will work with only a battery and it should be work with battery like 1 year. Can I only sleep SPI based lora modules ? I mean, I checked some modules they need a lot of current even with in stand by (1.5mA). So I want to sleep only lora module so microcontroller can work for taking sensor datas (for adxl345 microcontroller needs to work all the time).
LoRa is the on air protocol, LoRaWan the end to end protocol.
Hmm I see, I am going to use both of them same time I guess but I am not gonna use the lorawan library but I will post the datas through network with my own wifi or ethernet.
And it means, Only gateway use this Lorawan protocol right ?
