<p class="MsoNormal"><span lang="EN-NZ">Hi Tony<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-NZ">Have mucked around with firemonkey mostly seems OK once you get your head round the slightly different syntax etc<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-NZ"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-NZ">With BTLE for Android not sure if it has been well implemented seems to be missing a function RequestMTU which sets the data pack size for gatt Android<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-NZ">And as a result the default size of 23 is used (ios and win don’t appear to have this issue)<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-NZ">Had to do an ugly hack to set this to 75 my packet size<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-NZ">Also not sure of the Issue about disconnecting etc<o:p></o:p></span></p>
