Hi everyone,
I'm looking into using an old NB-IoT DevKit with the discontinued Quectel BC66 Module I received from a colleague of mine. Does anyone have any idea how I can still use this DevKit? Unfortunately, the AT command firmware does not seem to exist on the device anymore. The device doesnt respond with a "RDY" after the booting process. Any help is greatly appreciated.
Kind regards,
Ameer
Try sending "AT" without the quotes and see if it responds. If it doesn't respond, try downloading the latest firmware, you can request AT command firmware from the Quectel forums, just start a new thread and request AT firmware for BC66, similar to this one:

Then use Qflash to download it to the module
