@lupyuen ...the 1st time I heard about #lora was about 5 years ago when hired as a consultant to do an 'in-house' pilot project for one of the 'big 3' in #Detroit . Having spent over 10 years in another spread spectrum tech, #cdma , and once seeing how LoRa could actually have 'negative SNR' , I knew immediately its huge potential for #iot. Sadly, and as stated in the piece, many in the industry don't listen to us RF eng and get 'hyped' into the 'noise' - until now. Better late than never! 🔴

@lupyuen @gbraad Seeing it when it was released made me feel physically ill until I saw that it potentially had real T-Head cores.
It seems as with most things from BL, the BL808 needs some perspective added to make sense of what is going on.
You have made their products usable from the first time I encountered them. There is no other person who is fit to do what you do.

@lupyuen That is a mostly secure connection. I'd say that it's approximately as trustworthy as the molex connectors or jumpers. It reminds me of a Lineman's Splice for wiring.

@lupyuen how is NuttX hardware support compared to BL's SDKs? I think they have some sort of rust SDK or FreeRTOS.

@lupyuen I have the Sipeed M1s DOCK. Been thinking of doing something with it.
