Serin Serout possible wiring distance

[Ioannis]

Thanks for sharing. Regarding the serial communication, can you use the hardware serial port of the controller?

The I would suggest to use also the Hserin and wait for the response from the RF module instead of just PAUSE 1000. You can't be sure that the module responded in-time.

Hi Ioannis,

The pause 1000 is the 1 second no input then the +++ and then no input for 1 second. This is the format required to put the rf module into 'test' mode for RSSI output.

OK, I do not disagree. But when the module enters the AT command mode by +++, doesn't reply with some kind of acknowledge? An OK or something?

I am on a slow internet connection now and cannot download the data sheet of the module.

You are right it does do an "OK" back but after the one second of no activity.

To be honest so far I've ignored it in the software as it is only just about to be tested for real.

I appreciate your help. I should do a WAIT in there.

I'd prefer to do this in hardware serial port because it is much faster. Or at least the Debug and Debugin.

Some serial devices do respond very fast and had a case where Serin/Serout was unable to follow.

Not having any success getting the modules into test mode using the AT commands as per the code.

I'm saying this because the routine stops waiting for a signal strength report which isn't there. This means the routine to put it into test mode isn't working.

Anyone any suggestions ?

Can you post your code please?
