No ACK from Gateway #210

hello @CongducPham sir, I have an issue running the ping_pong code. When i run it using no-ACK version of the code I receive the following on my serial monitor:

no_ack

And when I run it with ACK I get the following on the serial monitor: with_ack Although in both the cases my gateway displays this: 2018-06-19-120459_1824x984_scrot

what can be the issue here? how can i receive packets with ACK in ping_pong code? Looking forward to your response. Regards.

Without ACK, there is no way of knowing if the message is received, hence the Serial monitor says pong received. With ACK, the pro mini is waiting for a reply to confirm that the message was received. In both cases the message is not received by the gateway.

There are several issues I see from your screenshot:

1/ there is state=2 when setting power at device, it is not normal. 2/ cr=4 is not a valid option at gw, the minimum is 5 to have the 4/5 mode.

Please be sure to have the same setting at both ends.
