TC55 Operating System GSM non-GMS BSP 01.65.04 Release Notes


TC55 is a ruggedized device based on Android for the enterprise market that blends the capabilities of a smart phone with those of a traditional enterprise PDA.
TC55 has a number of enterprise-grade features, including a touch-screen that can be used with gloves, support for stylus input for signatures, barcode capture capability and IP67 rating for dust and water protection.

It also features Extensions (MX) to make the Android operating system more enterprise ready, with security enhancements and hooks for device management tools, and is designed for a longer lifecycle than the typical smart phone.
TC55 is designed in response to customer feedback from using consumer-grade smart phones in the workplace, especially with the bring-your-own-device (BYOD) trend, where employees use their own choice of device for work.

With TC55 the workers can capture practically any type of data — from bar codes and signatures to photos, videos and NFC — improving on the job efficiency and customer service. The screen is optimized for Enterprise viewing, helping ensure the battery lasts a full shift.
And with a drop, tumble and environmental sealing specification you can count on, it has the durability required to serve your field workers for years.

Known issues, Tips and Workarounds



·   Charging may fail on the first attempt (rarely) the LED will blink red quickly to indicate this (114388)

To recover, reinsert the charger.

Charging a deeply-discharged battery will cause the LED to blink red slowly… this is normal and can last up to 8 minutes until the normal charging green LED is seen (114428)

This is normal behavior.

USB printing on a ZebraMZ220 doesn’t work (100574)

This printer is not supported by Android.                    

After inserting a T-mobile SIM (rarely) data service cannot be obtained (115307)

To recover, turn Airplane Mode On/Off. Note: this is a T-mobile network issue.

For a mixed deployment comprising broadcast and hidden SSID’s, the device cannot connect to a hidden SSID if the profile was added manually by selecting a broadcast SSID listed in "WiFi" Settings Page.(114289)

To workaround this problem, there are two solutions:


1.     Manually add the profile using the “Add network” option (Click on “+” in “WiFi” Settings Page)

2.     To configure programmatically, use the wifiConfiguration


 to create a profile that has the hidden SSID field parameter set to true. Here is a Code Sample to do this:


             WifiConfiguration configuration = new WifiConfiguration();

             configuration.hiddenSSID = true;

When in Silent Mode the volume button doesn't work while in the Decode Audio Feedback of DataWedge (116535)


User can go to any other screen and Vol+/- works, and will move out of silent mode.

Exchange and G-mail account folders are not localized when switch from one language to another (117486)

This is Android behavior.

Workaround: To close the application and reopen language is refreshed

When “Keep Wi-Fi On during Sleep” is set to “Never”, Standard Android WiFi API “getRSSI” returns incorrect value (always returns -200) after Suspend/Resume.


If "getRSSI" API is to be used, have "Keep Wi-Fi On during Sleep" set to "Always".

This policy may result in higher battery usage.    The user is advised to disable WiFi when not in use.
