Thank you for your reply Mike
I actually have more than one WiFi network running concurrently and I have observered that, according to the RRC, the signal strengths vary, with not always the nominated network being the strongest, hence the reason for my question.
At the moment I turn off all WiFi networks apart from the one I want to use, then make my connection. I normally have two operating, one with access to the internet and one without. In the future I could invisage some other network, not associated with me, causing problems. Hence, I would suggest the design choice of the choosing strongest WiFi signal is worthy of reevaluation.
From my perspective it would be really good to be able to nominate the specific WiFi network, if that is practical in the foreseeable future.
Thank you for you comment on the limitation of the WiFi chip
