Hi!
I have a problem with some sites that have good LTE and GSM connectivity. In these locations, some modems connect to the GSM network, even with a strong signal from the LTE network in the same region. So, to solve this problem I’m trying to change the radio access technology in a modem HL7692 with firmware RHL769x.2.26.180400.201802141030.x7120m_1
. The allowed modes are 1, 5, 8 and 9 and when I try to change to 8, for example, I’m getting a CME ERROR: 3.
Look at the snipned bellow:
Manufacturer of modem: Sierra Wireless
Type of modem: HL7692
Modem firmware version: RHL769x.2.26.180400.201802141030.x7120m_1
IMEI: 355465071111120
Serial number: VE851440900810AT+KSRAT?

AT+KSRAT=?
+KSRAT: (1,5,8,9)OK

can someone help with this issue?
