Thanks for your kind and hope your bluetooth operate successfully.
In fact I am not in Tehran. it seems the FT232 need a pcb to mount and can not be used in breadboard.
may I use this IC to connect every UART to usb port of computer? and is it easy?
At this stage I cant recognize the problem (may be the module is down or burst!!). Are you sure your module is ok????
could please send me some more circuit, datasheet, and any helpful about ft232.
is it programed by factory or need to be programed by user?
All seems ok.
I suggest you first test your module as follow:
1) disconnect the ft232 usb.
2) connect the VCC and GND to 3.3 volt.
3)connect the rest to GND and search the module by a cellphon or laptop bluetooth. can you find the module? if no, now connect the reset to VCC
and repeat the...
I guess there is some problem with your hardware setup. first check your hardware. or if possible, send me the complete circuit schematic that you are testing.
BTW, if you have a look at the text file you sent, it is clear that this code is not incomprehensible and random. because it repeat...
Attached is the datasheet and external commands that I received recently from the company.
I asked them about difference between aubtm21 and 23, and following is their answer:
"The difference of AUBTM-21 and AUBTM-23 is just the internal voltage is different,AUBTM-21 IS 1.8V and AUBTM-23 is 3.3v."
I would like to let all know that I asked the company for datasheet and they kindly sent me datasheet and AT commands.
It's pin configuration likes the AUBTM-21 and in fact it is overally as AUBTM-21 but some minor difference.
Dear friends;
I recently bought AUBTM-23 bluetooth module but I can not find its data sheet and pin configuration. could you help me with that please?
Lookforward to hearing from you,
Regrds,
E. E
thanks.
I want to use it as a inductor. But there is only one point to connect on PCB. Where is the other? should we connect the body of resonator as a second point to the ground or not?
Dear Sir/Madam
Recently we have bought some coaxial resonator (Trans-Tech SR8800LPQ1357BY). we want to use it for an oscillator but we find out it has only one lead to connect on PCB. Could you please help us with using this part.
Dose it have any other lead, for example its body or so?
Many...
Dear Meysam
Could you let me know finally did you run vncl1l? do you have the IC or you have also the evaluation board?
how much is it? could you program the firmware on vnc1l?
Thank you very much.
