Progamming RHF76-052 MCU's

Goodnight. I’m working with the RHF76-052, the module by its own, I mean out of Seeeduino Board. Im using it with the gps gy-neo6mv2 and an arduino mini-pro. The proyect consists on send a location to the gateway and also vizaulize it in a web page. I am interesiting on progamming the LoRa chip MCU’s insted of keep working with the arduino to reduce the power consumption.I’ve been searching information about this on internet and aslo in the chip manual, but I didn’t have any luck. I have been also searching for seeeduino schematic to analize the internal conections and try it, but I havent found any as well. I’ll be really grateful for any help!

Pd: I’ve attached the manual and the datasheet of the chip RHF76-052. (1.58 MB)
