ACK receive message

[elgebar777]

Hi, i have problem with connection between Raspberry and Arduino. When i set configuration raw on true ("gateway_conf": {.. "raw": true,) i get messege from Arduino, but Rasp does not sent ACK to Arduino. When i set RAW on false, my Rasp don't recognize any message - i didn't see "got first framing byte"

[CongducPham]

Why are you using the raw option? It is only used in very specific cases. What do you want to do exactly?

regards

I wish send string from Arduino to my Rasp with ACK, but Rasp dont send back any information. When I use raw:true mu Rasp can recognize mess from Arduino

[CongducPham]

You don't have to use raw mode, please set it to false. Then look at the ping ping example for sending data and requesting ack.

I am having the same issue. I am using a Feather M0 RFM95 and a Hope RFM95W on a RasPI 3 B. The M0 sends the "Ping" and the RasPI gateway receives the PING but the M0 never receives back the "PONG".

The message from the RasPi Gateway:

^$ACK requested by 8

Message from the M0:

Thanks, Kirby

[CongducPham]

When the gateway is sending an ack, you have to make sure that at the gateway, the lora_gateway program is compiled with the correct PABOOST settings that is needed by the radio module. Please read:

C. Pham,

Thanks for replying. I have this in the radio.makefile:

#options are: -DPABOOST -DMAX_DBM=v
#
CFLAGS=-DPABOOST -DMAX_DBM=14

I get this:

make lora_gateway_pi2

g++ -DPABOOST -DMAX_DBM=14 -DRASPBERRY -DRASPBERRY2 -DIS_RCV_GATEWAY -c lora_gateway.cpp -o lora_gateway_pi2.o
g++ -lrt -lpthread lora_gateway_pi2.o arduPi_pi2.o SX1272_pi2.o -o lora_gateway_pi2
rm -f lora_gateway
ln -s lora_gateway_pi2 ./lora_gateway

I don't know if this matters but when I start the gateway I get a message that says: ./lora_gateway: unrecognized option '--ndl'

[kkalbaugh]

I should have included the entire start up message:

|No it doesn't matter|

HopeRF RFM95W Transceiver Module.

[CongducPham]

So PABOOST setting is fine. If you have this setting and you don't receive the ack on the device then I don't know what is the issue.

@CongducPham , Hi, I have a similar problem with my gateway, Raspberry pi 3 + Adafruit RFM95W (868Mhz)... the arduino test client (ping pong) with the same radio module, correctly send the ping and in the stdout I clear read the packet with rssi -61 dbm, the gateway send the ack but arduino recives that only in a few meters range... when I get far nothing happen... I think is the PABOOST of gateway, so I compile the radio.makefile but ... nothing... How can I check if the PABOOST is on or off? thank you in advance! and greetings for your great job! Michele

[CongducPham]

What do mean by "so I compile the radio.makefile"? You have to uncomment the line CFLAGS=-DPABOOST, save the file and then run

make lora_gateway_pi2

again.
