Bluetooth 'Read Failed' Error, (iOS 13.1.3?)

So anyone from the team have any advice? Are there any known issues with iOS 13.1.3?

  • It’s running fine on all phones that don’t have iOS 13.1.3, but it’s not working on any that do have 13.1.3.
  • It was previously working on the same phones until they updated to 13.1.3, when it stopped receiving data
  • The data is received from an ESP32. I’ve tested multiple ESP32’s with a range of phones, it works on all except for those running 13.1.3

They can still scan, connect and transmit, but cannot receive.
