uplink delay after receiving a downlink message

[mluis1]

Thanks for the report.
Could you please provide more information on the downlink message(s) that you send to the end-device?

If possible it would be nice to have the frame contents. Example:
Downlink frame:
60 F5 EC EE 00 20 00 00 28 14 E2 CC

Configuration: ABP, ADR on, APP_TX_DUTYCYCLE 180000000, no ACK, dutycycle on, 3 default channels.
The downlink messages are coming from the LoRaWAN server.

Hi pdemil,

I wasn't able to reproduce the issue yet.

1. Are you testing with the sample applications?
2. Does this issue appear every time or sometimes?

[pdemil]

issue appears every time, but I will try again in v4.2. Closed.
