NO reply from AT Commands, with RFD 900+ #10

Open gbaweja opened 5 years ago

Hello Paul,

I am having kind of same issue. I am using Ubuntu 16.04. I downloaded the repository but make install gave error. So without installing any software or firmware on Ubuntu Linux. I installed minicom.

I have RFD 900+ radio. When I am on Minicom terminal window and I type "AT" as AT commands to see whats going on with the radio. I do not have anything back, I mean I do not get "OK". Could you please help me here, as I need help urgently.

Thank you for your time and help.

Hello,

First, it wont reply to AT commands until you push it to command mode via +++. You have to make sure minicom has hardware flow control disabled, and the serial speed is set correctly. It might be 115200, 57600, 38400 or 223200 depending on the firmware you are using.

Paul.

Hello Paul,

Thank you for your reply. I tried "+++" first and then "AT" command, but i get nothing in response. The baudrate for RFD 900+ i am using is 57600. I have hardware flow control disabled.

I cloned the "Sik" repository but when i write command "make install" in the Firmware directory, i get the following error.

Makefile:94: recipe for target 'install~bootloader~rfd900a' failed
make: *** [install~bootloader~rfd900a] Error 2

I didnt download anything related to RFD 900+. I have minicom and i am trying to send "AT" commands. Is there anything else i am doing wrong or is there any other piece i am missing.

Please suggest, thank you.

Hello Paul,

I was able to send AT commands to RFD 900, and I was also able to use RT commands. thank you for your help.

RFD 900 + modem Tx is connected to my laptop, and the Rx is connected to Raspberry Pi. Raspberry Pi has a python script that I want to run. Do you have an idea, how can I access that python script over RFD 900+ which is on Raspberry Pi?

Thank you for your time and help.
