BC26 has BC66 core #10

On the BC26 platform, the referenced core is bc66: https://github.com/Wiz-IO/platform-quectel/blob/207b87a64285f66ea6ccdc6f9e050210e8255044/boards/bc26.json#L5

I came here while investigating available NB-IoT platforms and I am confused. What are the differences between BC26 and BC66? From the specs they look the same so is one version a minor upgrade over the other? Also the BC26 seems to be more available on Chinese markets.

BC26 is only for China, BC66 is international version If you have BC26 module, try flash it with firmware for BC66 an test I not have module for tests....

Thanks for the clarification.

I found a cheap BC26 module on Electrodragon. I will order one and give it a try. Will report my results there.

@Wiz-IO I just reveived the BC26 module. Is the BC66NBR01A04V01 the latest B66 firmware? Is there a dedicated tool to flash the firmware?

Hi, you need to connect to your local Quectel support for this

Hi @Wiz-IO!

Flashing the BC26 with BC66 firmware works fine, thanks! I flashed the version 4 firmware with success and ran the info Arduino example with success. Quectel sent me version 7 of the firmware with QFlash. QFlash works fine just for flashing but doesn't have any of the advanced features of IoT FlashTool.

Does the official BC66 dev board have an auto reset? I have to very quickly power cycle the board in order to flash it. I think I destroyed the rst pin by connecting it to the 5V as I didn't initially had the schematic of my board.

Finally, what tool is used to flash the firmware with PlatformIO? I had a look at platform.json but tool-quectel repo is mostly empty. I expected some kind of bootstrapping with AT commands. https://github.com/Wiz-IO/platform-quectel/blob/207b87a64285f66ea6ccdc6f9e050210e8255044/platform.json#L49-L53

Thank you very much for your open-source project(s).

Hi :) in time I remove exe tools and replace with python scripts (reverse) here is BC flasher https://github.com/Wiz-IO/platform-quectel/blob/master/builder/frameworks/MT2625.py

The platform work on unix-like too

BTW: Arduino port work only with firmwares 4 and 5 for now and not need other firmwares I work over firmware 7 but I need time... About OpenCPU - there are no limits, but firmware 7 use SDK 1.4 - you can replace manualy or wait my update
