Hi Ioannis,

Unfortunately I'm stuck with these modules as the 'client' bought them.

I have his base requirements working 100% but I let myself in for more work when I mentioned signal strength output.

Trouble is the modules do not have any visual indication as to what they are doing. I'm working blind, other than turning leds on/off on my board at strategic points in the software.

I get confirmation after each AT command that the slave is in test mode.

It will not respond to anything else when in test mode other than "+++" guard characters for command mode, so I put in a time loop to turn test mode off later by software.

The master sits and waits after confirming it is in test mode. Then nothing. Both should be transmitting at 1 second intervals with RSSI information in db fed on the serial port from the master. They loopback the RSSI.

I do not have an interface to connect to my PC to test, besides that is no use anyway as the modules will be standalone. Testing on a PC just proves they work that way.

I also considered another set of rf modules originally from another manufacturer. They had red and green status leds on board. Red when TX, green when RX. Both on for config mode. Much more useful.

I chose the Ciseco modules because of power output and the support forum.

At first on the forum I thought they were a bit defensive and odd. Now they insult my admittedly limited intelligence and are downright rude.
I don't believe they read the replies carefully. I had to repeat what I had tested, even though the answer to what I had done was two posts up.

I've spent tens of hours on this. I'm leaving them just doing the basic function the 'client' wanted. On/off red/green light.

'Client' is a misnomer, I'm doing them for free.
