5-pin mystery connector ... Need to beg #Pine64 for the schematic 🙏

It's Alive!

Forbidden Candy 😂 ... Will it glow in the dark? 🤔

Yep it's an updated #PineDio Stack BL604 @PINE64 ... With LoRa SX1262!

https://lupyuen.github.io/articles/pinedio

#PineDio Stack #BL604 now comes with an interesting Baseboard 🤔

Yep it works fine with #BL602 Firmware 👍

Let's use an NB-IoT Antenna ... As the #LoRa Antenna for #PineDio Stack BL604 @PINE64 ... For now

https://lupyuen.github.io/articles/pinedio

Let's test the redesigned #PineDio Stack #BL604 with our #LoRaWAN Firmware ... And send some Sensor Data to The Things Network!

Here are the updated SPI Pins for #LoRa SX1262 on the redesigned #PineDio Stack BL604

https://github.com/lupyuen/lora-sx1262/blob/pinedio2/include/sx126x-board.h#L35-L49

We run this command to transmit #PineDio Stack's Internal Temperature to The Things Network over #LoRaWAN

Redesigned #PineDio Stack BL604 works great with #LoRaWAN and #TheThingsNetwork! 🎉 ... Though we're using an NB-IoT Antenna 😂

Trying to Bit Bang the ST7789 Display on the redesigned #PineDio Stack #BL604 ... Nope still not working, will try harder 🤔

https://github.com/lupyuen/bl_iot_sdk/tree/pinedio2/customer_app/pinedio_st7789_bitbang2

SPI Pins for ST7789 Display on the redesigned #PineDio Stack #BL604 ... Will verify this with the new schematic ... Why is LoRa so much easier to test than ST7789? 😭

https://github.com/lupyuen/bl_iot_sdk/blob/pinedio2/customer_app/pinedio_st7789_bitbang2/pinedio_st7789_bitbang2/display.h#L40-L71

@lupyuen Are pins other than DIO1 connected with the MCU?

@lupyuen Oh nevermind, I was thinking the SX127x chips, not as familiar with the SX1262

@captain_morgan Yep SX126x uses a different SPI Command Structure from SX127x ... And thankfully fewer pins 🙂

@lupyuen hopefully with the same functionality, I kinda find the 1276 annoying in that way, in firmware I completely ignore *which* pin the interrupt occurred on because I have to check IRQ flag regardless. glance the 126x datasheet on the todo list.

@captain_morgan yep SX126x is the "improved" SX127x, I think?

@captain_morgan I wrote 2 LoRa articles: One on SX1276, another on SX1262. You can see that SX1262 is a lot simpler for performing the same functions:
