My solution for rotctld

Gpredict
1

For those who use windows or those who use linux and have the problem that the arduino interface is ticked or the pc ticked, I found a precarious solution.
Is install Gpredict 1.4 . hamlib probe several and they all work, not so the Gpredict that the new one does not work, or the old one, but version 1.4 work good.

If put -m 601, 602, o 603 tild interface but -m 604 error up.

A few initial things to check:

  • is the port correct?
  • is your rotator supporting the protocol GS232a?
  • does it respond to anything if you connect a serial terminal directly to that port?
6

If you look, the first send of data makes it correct and then it does nothing. I am trying to solve with another soft that is not the rotctld because I do not understand how it handles everything.

Hello,

I have very similar problem. I have “rotctl_parse: NETROTCTL_RET 0”… My configuration is Gpredict 2.3.37 on Windows 10 and Hamlib (Rotctld) 4.3.1 on linux. Is there any progress in solving this problem?

8

Add.
But Gpredict v1.4 + Rotctld 4.3.1 works well… Newer version of Gpredict don’t work anymore.

v1.4 is absolutely outdated and does not work with any radio.
Please update and report issues!

Hi,
here https://community.libre.space/t/anyone-connected-alfaspid-rot2prog-usb-to-raspberry-pi/4407 I found a solution to my problem with rotctl (rotctld). In my case, there was a problem in timing between two commands. After adding the “-C post_write_delay=300” parameter, the current version now works well.
