HC-05 Arduino data freezing a moment

buffering algorithms to let some data build up before it passes it on,
BLE links, all like to add their own little delay
Which can sometimes all add up, like a rogue wave

in arduino. When that happens I jumping IOREF (reference voltage ) to pin 1 (TX), but in bluetooth. Is there anything similar or code. to past it

That was lost in translation. Type your statement into Google Translate, cut and paste the English translation here.

If you change the value of the IOREF you change all of the A/D channels. From the wording it sounds like you are using the delay() function, that is a no-no.

Incoherent, see reply #2. HC-05 is not a BLE device and probably innocent.

?It data freeze related to (((AT commands))) HC-05

Post a link, the HC-05 I find do not have any analog channel on them available to the user. The Arduino does, assuming it is an UNO which was not specified actually only has one A/D converter and multiplexes the channels one at a time. The A/D ref is the same for all conversions unless changed either by internal registers or external means. This is why we ask for schematics and links to the hardwares "Technical" information which was missing.
