After long searching, I have found newer firmware with bootloader for the HM-10 (v550).
CC2541hm10v550.zip (79.8 KB)
Hi there,
I've allready had flashed two fake HM-10 successfully, but this time I tried it with some out of the same lot again and the only thing that show's up in the cmd is "Waiting for respond form Arduino..." if I disconnect the HM-10 from the arduino then it knows nothing is there, any advise from you guys? The LED of the fake HM-10 which normaly blinked is now steady on and the AT commands do not work after the unsuccessfull flash 
I'm using:
- Arduino UNO
- Levelshifter
- Win7 Pro
I haven't changed any of my equipment in comparison to the last time...

I've successfully flashed the firmware, thank you!
But now it seems like the state pin isn't working anymore. Is there a way to bring this function back? Which pin on the chip (not the daughter board) should indicate an active connection?
(Also the onboard led is always off...)
Thanks in advance
Torsten

After long searching, I have found newer firmware with bootloader for the HM-10 (v550).
Thank you so much for posting this. It really helped me out of a jam.
I needed to get a demo up and running quickly on a BLE113 surface-mount module (which also uses the CC2541). I was able to successfully load and run the v550 firmware on the BLE113 module!
For anyone else that needs to know, the v550 firmware uses the following pins of the CC2541 for Txd and Rxd:
- P1_6 (UART1 TxD)
- P1_7 (UART1 RxD)
Guys! I really need your help! I was trying for the whole evening to flash a clone HM-10 module (https://www.aliexpress.com/item/Bluetooth-4-0-For-Arduino-Android-IOS-HM-10-BLE-CC2540-CC2541-Serial-Wireless-Module/32659958252.html?spm=a2g0s.9042311.0.0.27424c4daBAUBc) with the original HM-10 firmware since the lack in connectivity with Oreo devices. I have to say that I am new to arduino world. I only used it few times. So I apologise if I say something really stupid.
Basically I follow the different step but I get stock at the point when in the promt window the update should start. Below the pictures. I used an arduino uno and connected it following the scheme reported in the tutorial CC2541 / Arduino Uno
PIN 7 / 5
8 / 6
11 / 4
Does someone know how can I do it to make it work with windows 7 and an arduino uno?
Thank you very much.
Up...
If someone got it worked with my same hardware, please share the trick...
Thx!
Hi, guys,
I was successful.
Thank you very much!
You who put 5V directly are very crazy! Or very brave!
I put a 1k resistor between the Arduino and the HM-10.
Now the site has firmware version 603, someone tried to upgrade?
[HM-10 HM-11 firmware V603 released (2017/11/14 10:44:51)]
My antivirus blocked the download:
http://www.jnhuamao.cn/rom/HMSoft-10-2541-V603.zip
---> HMSoft-10-2541-V603.zip\HMConfigAssistant.exe Win32:Malware-gen <---
Some online antivirus are reporting viruses as well:
The v603 did not work here! 
The CCLoader.exe program shows the CC2540 chip.
The PDF document provided by the manufacturer says that the CC2540 chip is not the same as the CC2541, maybe the v603 firmware is for the CC2541 chip.
Due to the problem with antivirus, I could not follow the method described by the manufacturer, I used CCLoader, and after v603 I turned the v540.
The strange thing is that the site shows the details of the board with the firmware: V605, and download has only v603. ???
Note: When opening the port the Arduino Nano was reset, so I waited about 3 seconds and tried again (CTRL+C --> "^C"). In this way began the progressive counting of blocks, arrived at 512 for v540, and a little less for v603
For v540:

Now the Firm v603 has worked as IBEACON:
(P.S.: AT+VERR? and AT+VERS? shows HMSoft V604, Bug?)
1: Install the V540 with CCLoader.exe
2: Upgrade to V603 with HMSoft.exe
After upgrading the firmware, run the AT commands via serial port:
AT+RENEW Restores factory defaults
AT+RESET Reboot HM-10
AT Wait for OK
AT+MARJ0x1234 Set iBeacon Major number to 0x1234 (hexadecimal)
AT+MINO0xFA01 Set iBeacon Minor number to 0xFA01 (hexadecimal)
AT+ADVI5 Set advertising interval to 5 (546.25 milliseconds)
AT+NAMEDOPEY Set HM-10 module name to DOPEY. Make this unique.
AT+ADTY0 Advertising ScanResponse, Connectable
AT+IBEA1 Enable iBeacon mode
10.AT+DELO1 iBeacon Allowed to broadcast and scanning
11.AT+PWRM1 Don’t auto sleep
12.AT+RESET Reboot
Look this:
I tried slave mode and managed to pair with a smartphone, and I was able to send data through the UART serial port, but I could not make the system LED blink, does anyone know how to do it?
I already checked the LED with a multimeter, it turns on and is properly connected to the HM-10 pin
I already tried the command:
AT+PIO10 Set PIO1 output status (System LED)
Unconnected Output: 500ms High 500ms Low,
Connected output: High
To be able to pair with the smartphone:
(Of course the Smartphone must be compatible with Bluetooth LE [BLE: Low Energy])
AT+RENEW
AT+RESETAT+TYPE3 Set Module Bond Mode: Auth with PIN
Default PIN: 000000
To monitor connections:
AT+NOTI1 Set notify information: Notify
Link ESTABLISHED:
OK+CONN string through UART
Link LOSTED:
OK+LOST string through UARTAT+NOTP1 Set notify mode with address
OK+CONN:001122334455 String “001122334455” is the MAC address string
It not works like other simple Bluetooth module like HC-05 and HC-06
I found out what happened that the system LED did not blink,
I made a big mistake,
I soldered all the pins of the HM-10 on the daughter board. :-[
The daughter board has pin connection 24 and 31, so when I soldered, these pins stayed connected, as the pin 31 should be pulling down, the LED does not light up.
I realized this after monitoring the voltage the LED was receiving, it was only 0.006V (6mV), so I tested the continuity.
Fortunately on the daughter board has a track under the board, which makes this connection of these pins, so I had to cut it, and the LED came back to flash. 
I Followed this routine that make cc-41A(Fake board) to HM-10.
but I have a problem with AT command....
it doesn't work....
before I upload the binary file cc2541hm10v540, the AT commands worked
Now the Led on the board is blinking faster than before.
I have many fake board so I tried to upload by CCLoader.exe several times
How can I figure it out?....
I checked RX, TX Line swipping, and version 550 bin file....
This is the HM-10 v604 full firmware (with bootloader) in hex format: HM-10v604_full.hex
BTW, the latest versions of the firmware can be downloaded here http://www.huamaosoft.com/download_rom.asp?id=
What application should I use when connecting with my mobile phone? I do not accept 000000 as my PIN. 123456 accepts and connects. but the android applications do not connect properly? What is the reason?
Today at 06:49 pm
Hii... I faced a peculiar problem while trying to configure my AT-09 BLE Device's baud rate. I used the AT+BAUD2 which has set it to a baud rate of 2400 but now when I run any AT+ Command it prints ERROR twice on the console. But when I just use AT to check the connection the device returns ok. What might be the cause of this problem can anyone please help?
Can you do this in a Mac?
I have been trying to use your guide but I have not been able to do it on my Mac. Do you know what is the command in the terminal?
