Hi Renzo,…
I made a fire alarm system for a company, using E32-433T30D module, which is consists of 10 station/client, and 1 server in security room. I set the LoRa parameter using Ebyte software. I used your library and modified some of the codes. The cycle is like this, first the server will call the station by sending “call” message, after that if the station receive the correct call message it will send the feedback by sending the condition status message (safe/not), then the server will do the same cylce to another station. I use the Lora with these configuration : M0 and M1 are grounded, AUX-TX-RX are 4.7K pulled up, but I only use the TX-RX because in the beginning I thought it is enough using only TX-RX, and I couldn’t change the pcb anymore because it already installed on the site. At first trial it worked well, but after several hours (almost a day) some station didn’t respond anymore. They need to restart the system by turning it off then on again and it worked again. After several hours, the error happened again. I’ve attached the codes below.Could you give some suggestion how to solve it? Is there any method to restart the module automatically?
Thanks in advance… -
Hi Setyawan,
sorry if I answer you only now, but I’m returning this day at home.In the program, you put a cycle that sends a big quantity of messages without stopping and I think you ask too much to the devices, try to wait for more from one message to another, then put the
if (e32ttl.available() > 1)outside the cycle of sending and don’t use delay but check an elapsed time for sending and nothing for the receiving.
Bye Renzo

Hi Renzo,
Thanks for answering my question. Can you tell me which program did you mean? because I attach 2 program there. And I still didn’t get what you mean. As long as I know, I only sending a message at a time (if I’m not wrong).
Actually last time I tried to modified ny program and put `ResponseStatus rs = e32ttl.resetModule(); in the program. I found it from one of your forum. My concept is when there is no message from LoRa module to arduino, it will execute that instruction to restart the module. Is that correct?
Here I attach the modified programs. One is the server and the other is one of the station.
Thanks and warm regards,
Setyawan -
