this._discoveredPeripheralUUids.indexOf is not a function

[rugarci]

Once I have connected to a peripheral correctly, from time to time I get and error message and node-red stops

3 Jun 08:26:09 - [red] Uncaught Exception:

Anyone can help?

Thanks!

Facing the same problem. Were anyone of you able to find a solution to the problem @hotrock3 @rugarci

Encountering same problem. whether it is node-red-contrib-generic-ble@4.0.3 or 4.0.1, causing node-RED service to fail.

@dhruvjhalani95 No solution to this problem identified. Shifting to ESP32 and the use of MQTT instead of using ATMega328 with BLE. This is probably a better approach in the long run but I was trying to avoid buying more stuff.

Same issue here. RasPi 4 with latest node-red v3.0.2
node.js v18.17.1
linux 6.1.21-v8+ arm LE

Is there any other setup to connect to BLE/GATT devices using node-red?

Same issue here on a Raspberry Pi 4 with
Node-RED version: v4.0.8
Node.js version: v20.18.1
Linux 6.6.62+rpt-rpi-v8 arm64 LE

I have the same issue - any idea how to solve?
The nodes don't work under actual bookworm 64 Bit OS, but they are running smooth on a windows installation...
Node-Red is in Version 4.1.0 on both systems...
Is it possible that user rights or access rights of underlaying noble modules affect functionality?

Seems to be the same issue I discovered:
Issue #74

Try the patch at the end of the. At least no more crash here......
