Could you please help me? #11

Closed tomaskovacik closed 4 years ago

tomaskovacik commented 4 years ago

Could you please help me? I've got the module with the BK3254 and wired it up via UART. If I turn the module on it sends a few lines out (for example BT_CN), but I can't get it to respond to any comands listed in the datasheet. I don't know what I do wrong but I just want to rename my device.

most probably, you connect your TX pin to an incorrect pin of the module

Largebytetechnology commented 4 years ago

I have already checked the wiring (even with continuity test). Would a module without UART put out these startup commands? Because I'm not sure if it supports UART. The local shop I bought it from claims that it supports it, but I'm not sure.

the serial interface is on pin 10 and 11 of the module, if you connect it there then it can be only one of:

Is there anything to do other than setting the Baud Rate to 9600, select the COM port and sending the command: COM+SNAME+XXXXXXXXXXXXXXXX\r\n to change the name?

tomaskovacik commented 4 years ago

you have to have module with firmware >=1.2

Largebytetechnology commented 4 years ago

Is the version of the Firmware the version on the underside of the module?

Largebytetechnology commented 4 years ago

Now I found the problem. It was the dirty supply voltage for the RS232 to TTL converter. Now I can communicate with the module but I still can't change the name.

Is the version of the Firmware the version on the underside of the module?

correct

Largebytetechnology commented 4 years ago

My module has got v1.2 written on the bottom, so there is something wrong with the the command or some setting. I can give commands like Play/Pause (they work) but to COM+SNAME+BTBLUE\r\n it doesn't respond

tomaskovacik commented 4 years ago

what is module responce to COM+SNAME+TEST\r\n ?

Largebytetechnology commented 4 years ago

It doesn't respond at all. However it does respond to some of the other commands listed in the datasheet.

tomaskovacik commented 4 years ago

maybe firmware version make sens only if module came from HYT, check if any of 1.2 commands works: https://github.com/tomaskovacik/BK3254/wiki/Supported-commands-and-event-send-from-module

Largebytetechnology commented 4 years ago

It tells me: XZX-BK3254-V1. 1 Is there any way of updating the Firmware?

tomaskovacik commented 4 years ago

no there is not, this basicaly tell you that none of 1.2 firmware commands will works

Largebytetechnology commented 4 years ago

Ok thanks a lot for your help and time. Do you know were I could get a v1.2 module with all the Features unlocked and reasonable shipping time?

tomaskovacik commented 4 years ago

I got my modules from aliexpress, from last batch of orders (1pcs to check what firmware module has, there are 2, buttons on ADC or one button on one pin of module)

read readme for this repository, all is there, direct link tu product: https://www.aliexpress.com/item/32833631256.html
