I am experiencing the same issue described in this thread when I use an E303 modem with Spacebridge. When the light is cyan I am able to reach a webservice on the device, but when it turns to dark blue I cannot reach it anymore. When the color change happens it looks like it transitions the mode from 5,7 (HSDPA+HSUPA) to 5,4 (WCDMA). This appears to be normal behavior when the modem is idle, but doesn’t work properly with Spacebridge.
My temporary fix was to force the modem on GSM only (2G) using the following AT command: AT^SYSCFG=13,2,3FFFFFFF,1,2, but that isn’t really
a good long-term fix especially with 2G being phased out. Is this an issue on the Hologram side and/or is there a better workaround?
