 If using RadioLib then supported modules - modules, which are supported by [RadioLib](https://github.com/jgromes/RadioLib/wiki/Modules):
 - `SX1278` is a default module, for other `SX127x` modules need to modify module declarations in `loraprs_service.cpp` and `loraprs_service.h`
+  ```
+  static std::shared_ptr<SX1278> radio_;
+  ```
+  and
+  ```
+  radio_ = std::make_shared<SX1278>(new Module(config_.LoraPinSs, config_.LoraPinDio0, config_.LoraPinRst, RADIOLIB_NC));
+  ```
+  replace `SX1278` with your module name
 - `SX126x` is using `DIO1` pin for ISR instead of `DIO0`, compilation might fail and need manual rename `clearDio0Action` and `setDio0Action` to `clearDio1Action` and `setDio1Action`
 - other RadioLib module types - check [RadioLib documentation](https://github.com/jgromes/RadioLib/wiki/Modules), modify code accordingly, open Issue if help is needed
