sudo bash monitor.sh -t :syntax error: operand expected

Hi good day, currently I am running at setting -t (trigger mode), if I didn’t trigger the mode for quite period of time, I am getting syntax error:

./support/btle: line 310: [[: -: syntax error: operand expected (error token is “-”) monitor.sh: line 1773: -: syntax error: operand expected (error token is “-”) Terminated

`> starting monitor.sh (v. 0.2.200)...

I have encountered a similar bash syntax error. In the version of monitor.sh I have, the error is reported on line 1809, which is: rssi_change=$((rssi - rssi_latest)) I suspect the rssi value returned is not a number for some case(s). I have changed line 1800 from this: if [ -n "$rssi" ] && [ "${#rssi}" -lt "5" ] && [ "$uptime" -gt "$PREF_STARTUP_SETTLE_TIME" ]; then to add this check and so far seems better. if [ -n "$rssi" ] && [[ "$rssi" =~ ^[0-9-]+$ ]] && [ "${#rssi}" -lt "5" ] && [ "$uptime" -gt "$PREF_STARTUP_SETTLE_TIME" ]; then

I'm having the similar issue @tramanah. My error is as follows: monitor.sh: line 1777: -: syntax error: operand expected (error token is "-") Terminated.

I don't know if this helps but I have 2 usb bluetooth dongles from different manufacturers. However, they both use the Broadcom Corp BCM20702A0 chipset.

In my setup, I have Synology Debian VM setup. It seems when the app terminates, it disconnects my USB connection on the VM. Sometimes it will run for many hours and then sometimes it terminates in about 10-15 mins.

I do have a third usb bluettoth dongle. It's an ASUSTek ASUS USB-BT500 that seems to be rock solid but generates a bunch of the following timeout errors: Bluetooth: hci0: command 0x0419 tx timeout.

Let me know if you need more info/logs.
