    @Goeytex Yes a disappointing result for the HM-19's and much the same result as with my HM-10 fakes. Keen to try some NRF24L01+...

    UPDATE: I just tested a pair of HM-19 Bluetooth modules and the results are rather dismal sending data byte by byte as required by the...

    Thank you all for your help. I think that my next steps will be to buy another HC-05 to try and get back to where I was, and a CP2102...

    That sounds like a logical way to do things and well worth adopting @inglewoodpete (y)

    Yes, true. Depending on the project, I reserve (up to 4) byte registers (b0, b1, b2, b3) for use for flags. I then allocate byte...

    I have just discovered that you can only individually address bits up to bit31 (b3)...Is that correct?

    Yes, I should have taken my shoes and socks off and counted properly, rather than trying to calculate in my head!

    Thank you for the solution @inglewoodpete and @Jack Burns. I wasn't aware that you could address bits directly like that, so you...

    You are using b2, whose bits are individually addressable, so try the following: if bit24 = 0 and bit25 = 1 and w14=1000 and pinC.4=0...

    It looks like inglewoodpete has accidentally quoted the wrong bit numbers, as bit24 and bit25 belong to variable b3. For variable b2...

    Hi All, I want to use this particular line in a project: "if b2 bit 0 set and b2 bit 1 clear and w14=1000 and pinC.4=0 then gosub dim"...
