Deterministic nonces would be great! Here is an example what we do in Specter, but we can easily swap it with something else: ```python # root blinding seed of the...

Two python implementation that might be interesting for you: From Foundation Devices: https://github.com/Foundation-Devices/foundation-ur-py Implementation in Specter-DIY: https://github.com/diybitcoinhardware/f469-disco/tree/master/libs/common/microur

Can you describe your problem in more detail? - what device you are communicating to? model and ideally link to the datasheet - what is the command you have problems...

Not sure if it will help, but maybe try the following: change this line: https://github.com/stepansnigirev/ArduinoSerialToEthernet/blob/master/serial_to_ethernet/serial_to_ethernet.ino#L345 from ```c if(Serial1.available() > 0){ ``` to ```c while(Serial1.available() > 0){ ``` and just in...

UDP is only used to detect devices on the local network with `tools/udp_scan.py`. It helps to find out IP addresses of the gateways.

Hm, very interesting... I think single `Serial1.read()` operation is slower than reading into the buffer or string, and this caused problems. So I should probably update the code using strings...

Makes sense. We should notify about these inconsistencies at least in the logs. Warnings in the UI would be even better.
