txCharacteristic.setValue() doesn't notify central

[vovagorodok]

Peripheral: nano_33_iot (same issue with esp32dev)
Central: HP EliteBook 840 G1 with Kubuntu 23.10

When running data transfer by: https://github.com/vovagorodok/ArduinoBleOTA/blob/main/tools/uploader.sh
Central doesn't receive ack notification.
Peripheral side: https://github.com/vovagorodok/ArduinoBleOTA/blob/2c900594f3b9850dfd17ab0c8df5019fe3efb78c/src/ArduinoBleOtaClass.cpp#L107

Write req

Issue reproduces each time only on this laptop (checked on bluezero and bleak python libraries)

[vovagorodok]

Looks that changing transfer package size to 20 (23 (min mtu size) - 3 (bytes header size for write reserved by ble protocol)) helps, but negotiated MTU is higher than 23 . Any idea what can be the issue?
