Good day!
Where can you see this project of yours?
I am also very interested in the case when there are several transmitters and one LoRa receiver.

In reply to Uart Developer. I have a similar project, Keep the signals on one channel. On start-up, send a time signal pulse to all transmitters to give a start time stamp, then for each transmitter, stagger the signal transmission so they don't collide with each other, ie transmitter 1, go first, then #2 delayed 100ms etc, #3 delay 200ms. depends on packet size, but a surprising amount of data comes through.

Hi,
Thanks your great info. Your example code works for 1 transmitter + 1 receiver. Now I have 6 transmitters keep sending message to 1 receiver. may I know how the receiver receiver message from 5 transmitters?

how to set the channel and address for 5 transmitters,
and how to set are the channel and address settings for the recipient?

In reply to Samuel.

Almost the same here,

I use one transceiver as transmitter(A) and the other transceiver as receiver (B)
Transceiver A parameters are set with the following code:
0xC2 0x02 0x02 0x1A 0x17 0xc4

Transceiver B parameters are set with the following code:
0xC2 0x04 0x04 0x1A 0x17 0xc4

What i also did is that i increased the distance (to about 1.5 meter) because the transmiter yells at 1 Watt? But maybe this is still too close. Or maybe a too short distance doesnt matter.. Another thing i noticed, that i receive only one time the data and thats it.

So what i do is i send every second x04(high address) + x04(low address) + x17(channel) + 58 data bytes without any delays in between.

The first package of 58 bytes i receive. than thats it..

In reply to Sarah. you can use software serial example from arduino example. It will work.

Anyone has Arduino IDE example code for a simple version check?

Hi,
Does anybody know what is the actual purpose/usage of the
ADDH and ADDL?

does it need to change for each module?

thanks

In reply to Elisa Lee. I have a similar configuration for a home monitor i built. I send/receive data using a data structure where the first data is an ID, the receivers are set for a unique ID. The base loops through each ID, sends a request for data, and if the ID matches the sender, it will send data back to the base.

Hi Toni,

Hope that you made it worked with Raspberry since.
I am actually trying E32 with Raspberry 3 and can not receive the messages. Could you please share your insights?
Thanks,
Sam
