More about Named Data Networking (NDN)...

Interesting suggestion for upcoming #LoRa Devices by @PINE64 ... Should they run on Named Data Networking (NDN) over LoRa ... Instead of LoRaWAN? 🤔

Flashed the #LoRa Transmitter to @RAKwireless #WisBlock ... This Arduino program transmits "Hello" in a LoRa Packet every 5 seconds

How to Be a Good #OpenSource Project Owner

Let's test whether #LoRa SX1276 triggers GPIO Interrupts correctly on #BL602 ... When it receives a LoRa Packet ... The Interrupt Counters shall tell us

https://github.com/lupyuen/bl_iot_sdk/blob/lorarecv/customer_app/sdk_app_lora/sdk_app_lora/sx1276-board.c#L399-L428

My bad ... #BL602 High Level Trigger Interrupt = 高电平触发中断 = Trigger Interrupt on Logic High ... Nothing to do with priority 🤔

https://github.com/bouffalolab/bl_docs/tree/main/BL602_RM/zh_CN

Maybe #BL602 High Level Trigger Interrupt = High Priority Interrupt = Sync Interrupt? 🤔 ... Lemme check the original Chinese Reference Manual

https://github.com/bouffalolab/bl_docs/tree/main/BL602_RM/en

#BL602 GPIO Interrupts: Should we use Sync or Async Interrupts for #LoRa? 🤔 ... BL602 IoT SDK uses Async Interrupts to handle GPIO Buttons ... Let's do the same for LoRa
