We have a Quectel M66 module-based breakout board which we brought from here: https://evelta.com/m66-quad-band-gsm-gprs-breakout/. On the module, it is written M66FB-03-STD. We downloaded the M66 OpenCPU SDK from Quectel’s website and have successfully set up the development environment. Now after generating the bin file for example_gpio.c and flashing it using QFlash v4.19 successfully, the NETLIGHT on the board doesn’t work as expected. Also, when we try to open the debug TXD RXD port, we get garbage values in the serial monitor.
I noticed that M66 R2.0 does not support OpenCPU, so are M66FB and M66 R2.0 the same? And are M66FA and M66 R1.0 the same? I could not find any information related to this anywhere. Hoping anyone can help us out.
