Does anyone know how to send command to Maxstream RF module?

[Izzy]

Hello,
I was wondering if anyone here knows how to send Binary command to the MAXstream Xtend9 through PIC.

I tried with:

1. Change RT settings to 1

2. Turn CMD pin high

3. Send '6' ('6' is 0x36 in hex, which is the binary command to get the value of reveived signal strength)

4. Then poll of 2 byte data using Kbhit

5. Turn CMD pin low.


But this doesnot work.

Just call the maxstream people. Or do a web chat.


They are SUPER helpfull. They have allways gotten me
running in 15-20min.

I have used these in pairs a bunch. but only using
simple AT-command set. NOT binary.

So did you used At commadn Through the PIC?

How did you do it? I coulnt make it work when I tried.

Can to tell me how?

[treitmey]

No not from the PIC.
from the PC using there program XCTU.

Download that

then if you can tap into the serial, http://www.microsoft.com/technet/sysinternals/utilities/portmon.mspx
you could watch and see how they do it.

I was told it just used AT commands.

If you can't, perhaps I can find some free time. let me know.

Start by calling them, and/or using xctu.

I just remembered something VERY IMPORTANT.

the way you are able to send bin data without it being interpreted as
the AT commands, is that they require as fixed "guard" time before and
after the commands. I ran xctu and it shows it as 1000, ie I think that
is 1000mS or 1 sec.
The first thing xctu did was send "+++" and I think its waiting for a OK
Since I don't have the module right now,... that is all the farther I get.

Their modules act like a regular computer modem. There are the standard AT commands and then they also have some extended AT commands to set extra registers. The +++ string will put the modem into Command mode. The modem should echo with an OK. This is where you can enter new values into the various registers. If you download the manual it should show you the ones that are available.

The modem also has a timeout feature. Once in Command mode, if an AT command has not been entered within a specified time, I believe one second is default, it will return to data mode. You can send AT commands, with a PIC, simply with a printf() statement.

Thanks for the reply folks.

I will try using AT command as you guys said.

But I need to use Binary command because AT command takes time. I need to get the RSSI value after every few (say 50) milli second.
So it would be very nice if I can use binary.
