Pin correspondance atk-lora-01

Hey.
For use the esp32 with lora module, you preconise a module SX12xx.
I have a module atk-lora-01 but the pins no are the same.
I have à pins:

  • MDO
  • AUX
  • RXD
  • TXD
  • GND
  • VCC
    Can you help me for correspondance with the pins

SCK - GPIO5
MISO - GPIO19
MOSI - GPIO27
SS - GPIO18
RST - GPIO14
DI0 - GPIO26

Thanks.
Jean-Marc.

Can you share details for the module ? Ie a data sheet

commented

Thank you for your reply.
I don't have much for datasheet.
Here's what I was able to find.
Thank you for your hoped-for help.

I took a quick look at the data sheet and that board doesn't appear to be a direct replacement for a SX1278, but something else and does not have the appropriate connections to connect.

Thank for reponse.
Its a sx1278

Googling finds this - https://wiki-power.com/en/Lora通信-基于正点原子ATK-LORA-01模块/

Which indicates that it uses an 'AT' command set, versus the SX1278 which uses a SPI interface and registers

I expect that under the cover you would see a SX1278, and another chip controlling the SX1278. That is the one that is exposed via the pins.

I understand that it seems difficult to integrate it. I'll try with another module... Many thanks.

@NorthernMan54
Good evening
You were kind enough to inform me about my ATK-Lora-v3 (433) module and I thank you (1technophile Github).
You explain to me that this lora module uses AT commands and not SPI.
I just bought another lora module "E32 433" from Ebyte and I'm afraid I made the same mistake.
Can you try to explain or give me a link on the difference between the "AT" and "SPI" system.
My goal is to connect one of these modules with ESP32 to interact with OpenMqttGateway but I can't find any resources.
I am a little lost.
