I’d like to create a system communication using LoRa protocol between 2 devices, I don’t want to use TTN. I’m newbie with LoRa I’ve seen Seed provide SDK to use LoRaWAN but I don’t want to use gateway or server.
To be simple I have one device with LoRa-E5 and another device with another LoRa-E5, I’d like to be able to comunicate with LoRa between those devices, so it is End device to End device I think, is it possible ?
I am the same, and I opened this project. During compiling I get the following error in the application/target/radio_board_if.c
#error user to provide its board code or to call his board driver functions
I have the Lora-e5 on my own board, so dont know what to add here. If anyone has a small built project that you wish to share, then that would be much appreciated.
STM32CubeMX allow to select type of board configuration (DCDC, TCXO and TX RFO HP/LP/HP+LP support under Middelware/SUBGHZ_PHY
#error is changed to #warning user to provide its board code or to call his board driver functions.
Change compare to Nucleo board: Quick check on the website LoRa-E5 mini - Seeed Wiki (seeedstudio.com), search for "SDK Example Label" shows that Lora-e5 mini uses TCXO, RFO HP only with a DC/DC. A CP2102 on Usart1(PB6/PB7) as usart. So change in you projet and implement a BSP_RADIO_ConfigRFSwitch() like using PA4 & PA5, OFF=> both=0, Receive: PA4=1, PA5=0, Transmit = PA4=0, PA5=1 and adapt other GPIO to match this board.

Note that "LoRa" is just a modulation technique - you could put whatever protocol you like on top of that.
"LoRaWAN" is a protocol which uses (ie, is "on top of") LoRa modulation.
A complex system that works is invariably found to have evolved from a simple system that worked. A complex system designed from scratch never works and cannot be patched up to make it work.
Many thanks for the reply. Im quite new to Lora and using the Lora-e5, so not sure what DCDC, TCXO and TX RFO HP/LP/HP+LP are (HP/LP, high power and low power?) . Any pointers on these?
