Updated EM7565 to SWI9X50C_01.14.02.00 and now no Carrier aggregation

IoT Modules MC/EM Series

Just upgraded my EM7565 to the latest generic firmware and carrier aggregation is not working any longer. If I revert back to fw version: 01.07.02.00 GENERIC_002.004_001 it works with everything else being the same. Any ideas on what I might be missing?

Hi @scm

Did you use 9999999_9907259_SWI9X50C_01.14.02.00_00_GENERIC_002.035_000.exe file to update the EM7565 firmware?

This issue cannot be reproduced after I updated to the latest generic firmware EM7565 SWI9X50C_01.14.02.00.

The log file is attached.log.txt (327 Bytes)

Could you please provide some information about your module and SIM card using below commands?

Thank you for any help/insight. It looks like it should be doing CA but it never actually does and the speed drop from the old firmware does not make sense (nothing else has changed).
