Tagged: Arduino, E220, micropython, Raspberry
Ok, now I have tried to send a string with the following settings:
Sender
ADDH = 00
ADDL = 03
CHAN = 18
FIXED TRANSMISSION
RSSI Enabled
Here I use the Arduino library.
and call the function as follows:
ResponseStatus rs = e220ttl.sendFixedMessage(0, DESTINATION_ADDL, 18, "Hello, world?");
Receiver
ADDH = 00
ADDL = 03
CHAN = 18
FIXED TRANSMISSION
RSSI Enabled
Here I use the Micropython library as follows:
while True:
if lora.available() > 0:
...
Unfortunately, the receiver does not receive a string.
Hi woto,
you have configured the Address and Channel for transparent transmission and set fixed transmission.
Follow these tutorials to send fixed message

this is for E32 and micropython but you can get some ideas

Hi Renzo,
Thank you very much.
Sometimes i can’t see the wood for the trees (German proverb).
So thank you very much.
best regards
Woto
Sorry Woto,
if you set the ADDH, ADDL, and CHAN with the same value, you have configured the devices to communicate in transparent transmission.
To use fixed transmission, you must set a different ADDH or ADDL and send the message from the first by setting the receiver’s destination address.
So, if you have configured the sender
ADDH = 00
ADDL = 03
CHAN = 18
you must configure the receiver
ADDH = 00
ADDL = 04
CHAN = 18
and in the sender
ResponseStatus rs = e220ttl.sendFixedMessage(0, 4, 18, "Hello, world?");
But I think you must check the articles, they can be more clean.
Bye Renzo
