#BL602 handles #LoRa Interrupts ... With an array of Events

https://lupyuen.github.io/articles/lora2?37#lora-events

Simple #BL602 Background Task that reads an Event Queue ... And handles #LoRa packets

https://lupyuen.github.io/articles/lora2?36#receive-event

How we register the #BL602 GPIO Handler Functions ... For #LoRa SX1276 pins DIO0 to DIO5 ... *pant pant*

What's inside our #BL602 GPIO Interrupt Handler ... That handles #LoRa SX1276 Interrupts

https://lupyuen.github.io/articles/lora2?22#gpio-interrupt-handler

#BL602 receives #LoRa Packets the power-efficient way ... With Receive Timeout

https://lupyuen.github.io/articles/lora2?9#receive-lora-packet

Here's how we init the #BL602 #LoRa Driver to receive LoRa Packets

https://lupyuen.github.io/articles/lora2?7#initialise-lora-transceiver

#LoRa SX1276 connected to #BL602 ... How many pins do we really need?

https://lupyuen.github.io/articles/lora2?6#connect-bl602-to-lora-transceiver

Here's how we connect #RISCV #PineCone #BL602 @PINE64 to a #LoRa Transceiver: Semtech SX1276 or Hope RF96

https://lupyuen.github.io/articles/lora2?3#connect-bl602-to-lora-transceiver

Why does #PineCone #BL602 @PINE64 receive #LoRa Packets? ... So that it can join secure, managed #LoRaWAN Networks!

https://lupyuen.github.io/articles/lora2?2

#PineCone #BL602 @PINE64 receiving #LoRa Packets from RAKwireless #WisBlock ... All shall be explained in this article. Thanks for reading this looong thread 🙏

#PineCone #BL602 @PINE64 with #LoRa SX1276 ... Here's how the LoRa Timer works

Timers for #BL602 #LoRa Driver ... Implemented with NimBLE Porting Layer

https://github.com/lupyuen/bl_iot_sdk/blob/lorarecv/customer_app/sdk_app_lora/sdk_app_lora/sx1276.c#L215-L307

#RISCV #PineCone #BL602 @PINE64 connected to #LoRa SX1276 / RF96 Transceiver ... Including pins DIO0 to DIO3

https://github.com/lupyuen/bl_iot_sdk/blob/lorarecv/customer_app/sdk_app_lora/sdk_app_lora/sx1276.h#L24-L39

#BL602 #LoRa Driver creates hundreds of SPI DMA Requests ... Each request reads / writes only ONE byte! 🙄 ... Note to future self: Combine the SPI DMA Requests

https://github.com/lupyuen/bl_iot_sdk/blob/lorarecv/customer_app/sdk_app_lora/sdk_app_lora/sx1276.c#L265-L306

#BL602 receives 4 #LoRa Packets by executing 458 SPI requests ... Great load test for SPI 👍

https://github.com/lupyuen/bl_iot_sdk/blob/lorarecv/customer_app/sdk_app_lora/sdk_app_lora/demo.c

Here are the #BL602 #LoRa Timer Functions that we shall implement with NimBLE Porting Layer

https://github.com/lupyuen/bl_iot_sdk/blob/lorarecv/customer_app/sdk_app_lora/sdk_app_lora/sx1276.c#L214-L263

Swarm's Satellites Take #LoRa Sky-High

https://spectrum.ieee.org/tech-talk/telecom/wireless/swarm-takes-lora-skyhigh

Let's do #BL602 #LoRa Receive Timeout with these Callout Functions from the NimBLE Porting Layer

https://lupyuen.github.io/pinetime-rust-mynewt/articles/dfu#nimble-callout-functions

To conserve battery power, #LoRa Sensors don't always listen for incoming packets ... They listen for a few seconds then go back to sleep. 😴 LoRa Receive Timeout is the last thing we shall implement for #BL602

https://github.com/lupyuen/bl_iot_sdk/blob/lorarecv/customer_app/sdk_app_lora/sdk_app_lora/demo.c#L207-L215

#PineCone #BL602 @PINE64 receives #LoRa Packets from RAKwireless #WisBlock ... Almost finished! One more thang ...
