Got two Q64-001 out of box.
Need to replace GR-47 in simple AT-command mode device (send SMS when needed).
But Q64 do not answer to AT commands in usual way, only garbage returned.
Does it require additional flashing? GR-plugin is already installed or not?
Thanks in advance.
I had to order my module specifically with the GR64 plugin. YOu need to request it from your supplier.
Then AT+CGMR to check version of plugin.
AT+WOPEN to run application.
And it sould run everytime it is restarted, until stopped.
