Due to my involvement in a Guatemala RACHEL project, I am asked to demonstrate RACHEL-PI’s. I have set up three, one each in English, French and Spanish. I would like to run them all simultaneously to give the audience the ability to log into any one. However, the WiFi network name in each case is RPI. Is there a simple way that I can change the network name to something like RPI-EN, RPI-FR and RPI-ES so that the aurdience members can choose the language version that they want?
