i2cProcQueue >> IntegerDivideByZero

Hi I use this library to control i2c devices via BLE to send commands from mobile to ESP32. My problem is that when I send many commands I get this error
Guru Meditation Error: Core 1 panic'ed (IntegerDivideByZero). Exception was unhandled.
So I dissasembly the code and find the error in this function i2cProcQueue.
I google this error and find that this error is due to unsafe thread crossing.
the driver or BLE is multithread, so I dont know how to use this code without broke the multithread.
I think I have to lock the thread when I use the i2c.write and/or i2c.read.
I think this option shuld by buildin the library
thank you
probably because you are using IRQs? I2C locking/unlocking is not done by this library because its not standard arduino. however, if you have a way to add it without breaking other boards, please submit a PR!
closing now because this is not something we are planning on adding ourselves
Finaly I find the problem.
you cant resend Start Command before Stop. you have to stop old request and then send the new request
