3.Upgrade Firmware
To upgrade the Lora module, First we should make the module get into Boot mode. We should switch the P1 pin make the Boot pin connection with 3.3V Pin. Then reset the module, Operate according to the steps:
1.Open the Flash Loader Demonstrator tool，Set the serial port parameters;
2.Click the “NEXT” button, arrive the following interface;
3.The again the “Next” button，Choose STM32L1_Cat2-128K;
4.Choose “Download to device”，Set the path to the new firmware, and click “NEXT” button;
5.Upgrading;
6.Upgrade Successful.
