We are going to try Wavecom modules for our development, and Q2686 seems to be ok for our applications. But we have some questions which either not answered in available documentation, or we were unable to find exact answers. Maybe someone can shortly comment them. Sorry for really newbie questions, we do not ask for deep details, just for short “Yes/No/Look here…”. Thanks in advance!
1. Q2686 core.
It is said about ARM9. Can you tell more details about used ARM core in this product? The main purpose is to find more low-level information about the CPU core.
2. Free memory for OpenAT application.
How much RAM and Flash are, in general, available for user application in Q2686?
3. Firmware revision.
It is available for us to get Q2686H-431 V6.63. Is it compatible with V7.x firmware?
4. OpenAT Software Suite.
The Wavecom offers the 2.12 version only for Q2686. At the same time the 3.21 release is available for other products. As we realized, 3.21 is Eclipse-based.
There are no any device-dependand settings in 3.21 at first glance. But is the 3.21 suite compatible with Q2686 modules?
5. Series-related features.
We have found an old PDF document which lists modules series like Q2686H-430 with their features. But our supplier offers -431 series, and we were unable to find exact features list for 431. Can anybody point us to the original document which includes these modules as well?
6. C-GPS plugin.
Which hardware modules (exact numbers) are recommended for this product?
As far as we understand, we can use C-GPS plugin only if we use original Opus-based GPS module (which do you recommend?). Is it compatible with some other GPS receivers which provide, at least, NMEA compatibility?
7. Internet plugin.
We can get modules with I3.11 mark in the name as well as without it. We think that it is the V3.11 Wavecom Internet plugin version.
Can these modules be upgraded to I4.xx version? There is PDF documents availale for 3.11 and for 4.01, but we unsure if we can upgrade I3.11 modules to 4.01 or if we can use 4.01 Internet features on modules which supplied without I3.11 label?
There is no downloadable documentation available for Bluetooth for Q2686 modules. Are they compatible with Bluetooth? Which RF module should we use with it, if yes?
9. Digital Audio interface.
We wish to play MP3 files by the device. Can this inteface be used? Are there any sample applications for this interface? Can this interface be used with PCM1770PW DAC and software MP3 decoder? Please note that it is not about playing into GSM network, it is about playing files through external hardware DAC. The GSM network will be used only for GPRS/Internet services.
As far as wee understand, we can use it for Q2686. Does the loader support the firmware protection (encryption)? Or can it be replaced by custom-made loader which does?
Thanks again if you still read this list
