Problems with gpio_install_isr_service / ESP_INTR_FLAG_IRAM about ttn-esp32 HOT 3 CLOSED

I'm afraid I can't help you with PlatformIO. I'm struggling myself to get it working. As far as I can tell, the PlatformIO builder is not capable of using third-party components.

If you want to experiment yourself, you definitely want to use the dev branch of this library.

I had same and some more problems to get ttn-esp32 running using platformio and esp-idf. But now its working. See working example see here: https://github.com/vrees/Esp32LoraBoard

To get it running I had to change following:

• copied dev branch of ttn-esp32 in lib subdir of my platformio project
• in main.cpp #include "driver/gpio.h" in oder to get rid of error mentioned by @marcel151
• Due to a problem wth AES encryption "undefined reference to lmic_aes_encrypt" I had to switch to software encryption by changing 2 files. This works for me just now. Does somebody know how to use hardware encryption correctly?

src/lmic/config.h
#define USE_ORIGINAL_AES

src/aes/lmic_aes.c
line 260: u4_t t0, t1=0, t2, t3;

• added shutdown method to reduce deep sleep current of Lora chip

void TheThingsNetwork::shutdown() { ttn_hal.enterCriticalSection(); LMIC_shutdown(); waitingReason = eWaitingNone; if (lmicEventQueue != nullptr) { xQueueReset(lmicEventQueue); } ttn_hal.leaveCriticalSection(); }

My system:
VSCode 1.45.1
Espressif 32 Platform displayed in 'PIO Home' 1.12.1
Linux Mint

I've updated the wiki Page Using PlatformIO with the latest information about using PlatformIO.
