compiler warning of easyloragaeway

[skyladle]

hi all, hereinafter a compiler warning while I compile EasyLoraGateway , is it ok ? how to fix and clean the warning.

We use HTTP FOTA to help the gateway to get new firmware from MQTT message. Not working yet.

Option 1: You can try to get the latest library from https://github.com/nhatuan84/esp32-http-fota Wiki: https://github.com/IoTThinks/EasyLoraGateway/wiki/Compile-Easy-LoRa-Gateway#1-install-third-party-library

Option 2: You can simply remove it in line 55 as we are not using it yet. https://github.com/IoTThinks/EasyLoraGateway/blob/master/EasyLoraGateway/EasyLoraGateway.h

Option 3: You can ignore those warnings now if you can still compile it. We will fix it later.

Thanks a lot.

Hi IoTthink hardware : https://www.aliexpress.com/item/1-Pcs-TTGO-LORA32-V2-0-433-868Mhz-ESP32-LoRa-OLED-0-96-Inch-Blue-Display/32847499968.html?

but there is a core 1 panic while run the easyloragateway. something I do wrong? please advise,thanks

We official support this board. You may want to order the board at info@cloudfermi.com https://github.com/IoTThinks/EasyLoraGateway/wiki/Hardware-guide-for-Easy-Lora-Gateway#11-cloudfermi-som-esp32-3-lora-sx1278-433mhz---recommended

For Heltec board, we haven't tested the source code yet. We might start to support Heltec/TTGO board next week. Stay tuned.

[IoTThinks]

Mostly likely is the PIN mapping difference. You can check the PIN mapping in https://github.com/IoTThinks/EasyLoraGateway/blob/master/EasyLoraGateway/EasyLoraGateway.h

And change it to your board.

[IoTThinks]

If you comment the setupLoRa() method and the problem goes away, then the issue may be with the LoRa library from Sandeep Mistry. You can try to install his LoRa lib version 0.3.0 instead.

BTW, the pin mapping issue for Heltec/TTGO is not supported yet.

One of our own board seems to hit similar issue below.

Hi Iotthink, comment the setupLoRa and install Sandeep Mistry 0.3.0 , the panic is still there i aslo copy below TTGO pin mapping to easyloragateway.h
waiting for good news of support on TTGO. hardware suppose not far to cloudfermi.

define SCK 5 // GPIO5 -- SX1278's SCK

define MISO 19 // GPIO19 -- SX1278's MISO

define MOSI 27 // GPIO27 -- SX1278's MOSI

define SS 18 // GPIO18 -- SX1278's CS

define RST 14 // GPIO14 -- SX1278's RESET

define DI0 26 // GPIO26 -- SX1278's IRQ(Interrupt Request)

keep look into how come the panic there on TTGO.

[IoTThinks]

Hi, We will try to test the source code in Heltec (similar to TTGO) over the weekend. It should be related to the PIn or WIFi/ETH difference.

We expect to have something for you early next week. Stay tuned.
