@lupyuen I might have some insight into the SX1276? issue. It just occurred to me what to do.

Try using sudo and lsusb -v to measure the power being allocated to the BL602 board. I had readings of 98mA. An ammeter would work too. I don't think it's getting the power to emit more radiation.

@AmpBenzScientist Interesting... so we think BL602 might not have sufficient power for the LoRa Module?

Here's what I observed...

(1) BL602 + SX1276 seems to be emitting the right power (see the red chirp)...

(2) But BL602 + SX1262 seems to be emitting much less power (the faint chirp)...

If it's a power problem, why is SX1262 affected but not SX1276 πŸ€”

@PawelK @lupyuen These are very different transceivers. The SX1262 might take more energy but the bandwidth is closer to dial up speeds. That's almost double the SX1276. The SX1276 looks like it's losing on all levels. The transmission is a bit more sophisticated and I will need to review the SDR readings to try to better understand what is going on here.

@PawelK @lupyuen It's just a product from Pine. I am not aware of a product they have made that has worked without a massive community effort. Pine makes hardware. The community makes the hardware work. When I got my Braveheart I thought it was broken after a couple of uses. I took it completely apart and photographed it.

It was not broken by me. The battery discharges when powered off and dies after a couple days. I found out why it was getting so hot during use and recommended thermal pads to the developers.

Lee is likely the reason why Pine didn't die. As far as I've seen, he's been involved with every product that they have made. Imagine buying a product that doesn't work at all, working to make it work and never getting paid for it. That's what we do. It's for the community, it's for the knowledge we gain and most importantly for the future.
