Function "readLine()" & readtimeout

Hi,
some issues with function "readLine()":

• "readLine()" contains a while loop which can be left when variable "ed" is reduced to zero. Problem is, that ed is initially set to the value of 'readtimeout', but readtimeout is not set all the time and initially zero.
• if during this (long) while loop the bluetooth connnection is lost, the while loop will not be informed and continues to run.

To overcome this, something like the following change might help:

uint8_t readLine(void)
{
uint8_t byte;
uint8_t counter = 0;
uint32_t ed = readtimeout; // not really needed here, if not initialized with a proper value

while (btConnected) // without a BT connection don't try to read from the BT serial line
{
while (!SerialBT.available()) {
if (--ed == 0 || !btConnected ) return 0; // leave the loop if BT connection is lost
}
ed = readtimeout;
byte = SerialBT.read();
if (byte == 0xFF) continue; //TODO skip to start byte instead
...

Just an idea, code not tested so far.

Peter

Reconnecting after switching the ESP32 on?

First of all, thanks for the code.
Not an issue, but just a question: I observed, that the 705 does not reconnect automatically, when I switched the esp32 off and on again. (setting "auotconnect" on 705 is "on"). The 705 will only reconnect in that case, when I switch the 705 off and on or if I manually connect within the bluetooth settings. So, is this the general behavior or a bug of the 705?
Thanks
