Which RIL version you are using now?
@Bean.Wang-Q We are using RIL driver Quectel_Android_RIL_Driver_V3.6.24_Release_1.5 for EC25 GSM mini PCI.
Please try the 3.6.50 I just sent, if it still not working, please create a e-service ticket to Quectel.
@Bean.Wang-Q We are using version 3.6.40, but it still sends the AT+QSCAN command during manual network searching, and the response is an ERROR.
Sorry to hear about that. We can not solve the problem in the forum. Please create a ticket to Quectel.
