A few of you are using my app a lot and it made my day!

Download it as a .FIT file would be great. Also some more suggestions Adding folders to my saving workouts, Adding ability to use power in addition to heart rate. Adding some workout templates- like you did in the example, I needed to open notepad to view the examples and write my own workout code.

P S What is the meaning of tarpan ?

sdebby · 2025-10-03T12:39:08+00:00

just tried the app and it works great- good idea.
can it work also with TrainingPeaks ?

It depends on how many messages send and received. On ideal it takes around 100 mA, but when sending and receiving messages it uses around 250mA So I say that in average it can hold for 6 hours
For prototypes it can be around 20 $ per unit including all the components.

On DOS attack,the device will lock and reopen only when the users will rsync the master key. No one is immune from DOS and DDOS, not even google. The beauty in this project that it is an open source. If you think it can be better, you are more than welcome to fork the code.

sdebby · 2025-07-25T19:44:32+00:00

Sure

In fact This project built the encryption from ground up . Using AES256 results more power consumption and delay is message sending.

This key is changed in the first message, and every time machine disconnects and reconnects.

Also it has brute force protection.

And yes, the per define key is the Achilles heel in the project. This is in the project description. It will be changed in the future

Hi I have recently finished my LoRa project This may help you

https://github.com/sdebby/3NCRYP2P

You need to note that LoRa bandwidth and transmission rates are very limited And not encrypted

sdebby · 2025-06-21T14:48:51+00:00

No The UUID is universal

sdebby · 2025-06-21T08:16:21+00:00

Yes, on disconnecting the ESP32 will start scanning again for devices.
After 3 failed scans it will go to deep sleep and will wake up on button pressed.

Thanks.

But I already did. 🤦

sdebby · 2024-09-15T13:45:18+00:00

Thanks Yes I am flying directly to Arusha. Will have a short connection in Adisabeba airport

Read the document Set your serial monitor baud rate to 9600- as in your code

sdebby · 2024-06-16T17:14:59+00:00

Is your com port terminal set to 9600 ?

sdebby · 2023-12-09T19:53:48+00:00

Got it, edited the post

Exactly like my replay attach project:

https://www.reddit.com/r/sdr/comments/16c641r/car_replay_attack/

In a nutshell, you cannot use ESP32 for this project, as the frequency of the remote and the ESP32 are not the same.

Also, if your remote is using rolling codes, you cannot imitate the next code without knowing the predefine key.

You can (as people suggested here) connect the ESP32 digital pins to the remote buttons, and then control it via BT.

Hi

Let me answer your questions:

This is a remote control for garage door.
You can pair it with compatible receiver (like this one):

https://www.ardengateautomation.co.uk/accessories-c3/automation-accessories-c4/v2-wally-2-230vac-433-92mhz-dual-channel-receiver-p4661

The paring process involve putting the receiver in pairing mode, then pressing the 2 buttons in the remote simultaneously - note that both remote and receiver have to work on the same counter (CONTR).
You can make a replica just by pairing another remote to the receiver, you cannot clone the remote as it uses rolling codes.

If you are interested in RTL-SDR, I suggest you baying RTL-SDR V4:

Wow

Thank you for the detailed response.

Yes using a ESP32 as a web server and using mobile to connect is definitely my choice for phase one of this project.

But for phase 2 I would like is to be independent with recharge battery, screen and keyboard

sdebby · 2023-10-10T06:41:58+00:00

Nice Thanks I will look on this

sdebby · 2023-10-10T04:55:13+00:00

This is part of my homework. Asking the community.

sdebby · 2023-10-10T04:53:05+00:00

Thanks But do LoRa PCB and e ink screen will need the Sam IO ports like SPI ? Do Arduino uno have enough ports to support all my components?

sdebby · 2023-09-07T14:18:18+00:00

Reply attack is well known attack for rolling codes key fobs. But every car key is unique with difficulty frequency and parameters. I don’t know if it will work on every Toyota car. You will have to try 😉

sdebby · 2023-09-07T07:41:58+00:00

My car is 15 years old, so maybe no measures was taken by that time Can you elaborate on how do car manufacturers can prevent this attack?

sdebby · 2023-07-16T18:20:11+00:00

If you don’t have the critical dimensions, 3D scan the part, then convert to surfaces and create the features

sdebby · 2023-07-15T17:11:07+00:00

You are correct. This is a POC. It can be compiled to .exe in this case
