I was wondering if there are already people here who had the pleasure playing with the next generation of Gemalto's Java 3G modules? I have in mind to use the EHS6 in a project and there for I am interested in some hands-on experiences.
Like how is the 3G speed? And is the flash memory faster then the TC65i? Is the overal java execution performance improved?

Hello!
As for me, I don't need more connection speed, but I do want more processing power and more memory. That's why I hope I will use BGS5 - it has 5 MB RAM! And 10 MB of flash, but flash is not so important for me.

Hello,
I am using EHS5 with JAVA. Some AT commands are different than TC65
family. It seems to be OK, but shared GPIOs are too stupid.

What do you mean by shared GPIO? And can you really notice a performance upgrade caused by the ARM11 CPU and more RAM?

Hello,
TC65 has 10 GPIO, two serial ports and SPI/I2C interface.
EHS5 E -JAVA more GPIO bud they are shared by serial ports and SPI or I2C interface. SPI lines are shared between SPI and ASC1 and GPIO.
I use two serial ports and SPI lines in my project on TC65i, but on EHS5 it is impossimble, I have to decide ASC1 or SPI.
I use all 10 GPIO and two serial ports on TC65, but I don't have enough GPIO on EHS5 in this configuration.
It is not tragedy, because I am thinking about I2C IO expander for our projects.
I didn't try any performance test, because TC65i is already fast to me. I am happy with data transfer speed, speed of re-connection after data inactivity.
When TC65i is connected to GPRS, but no sending data for long time (10-30 min.), request-response time is up to 10 seconds.
EHS5 is better, request-response time is 1 second.
The best issue EHS5 - when you start this modem, all serial ports will go to sleep after one or two minutes (by default).
You have to setup non-sleep mode for serial ports:
at^spow=1,0,0
Warning: do not use at^spow=0,0,0 - I killed both serial ports on my modem :) . Last chance, connect to USB and use at^spow=1,0,0 .
When you need ASC1, you have to setup:
AT^SCFG="Gpio/mode/SPI","gpio"
AT^SCFG="Gpio/mode/ASC1","std"
at^scfg="Serial/Interface/Allocation","1"
Best regard
