Send to broadcast address which is 255.

You may also play with the MY_SLEEP_TRANSPORT_RECONNECT_TIMEOUT_MS directive if your RFM95 modem setting are too slow/long air time/repeater parent...

Pcbway do produce better finished pcb, but the big advantage of jlc is their SMT service

Sck = 15
Miso = 14
Mosi = 16
You choose SS and IRQ from available gpio

I'm using the sleepRemainingMs function for that and it works if accuracy is not important

They are programmed with the platform that you are using, assuming it support them.

@Anticimex more important is to set different network id or you'll have lot of collisions and lost packets

99% of the nacks are radio/power issues
You may recheck them carefully

You should define MY_SIGNAL_REPORT_ENABLED

@nagelc
I kept all setting to default except the maintain window =8s
So the SERIN reg is: 0x0031ED10

@NeverDie
With the fresnel and the wide angle 1598 it's ~ 7m

@NeverDie
Excelitas PYD1588/1598 are the best I've used, running now for years without a single false alert.
Fully integrated, 1.8V and only 3uA

If you are using pubsubclient, then

bool PubSubClient::connected()

should do the trick

I haven't ordered from them post covid-19 , but they used to be very reliable.

Well, i don't know if it is a timing issue or a hardware issue, but increasing the RFM95_POWERUP_DELAY_MS from 10 to 100ms solved the issue.
Now testing range improvement over rfm69h, will report back.
@tekka , Great work !

I'm trying to use the MY_RFM95_RFM69_COMPATIBILITY options but it does not pass the RFM95_sanityCheck.

Code compile without warning, and gateway is working fine with simple RFM95 driver.
Using esp8266 and arduino 1.8.13.

Switch to tantalum if you have space, much better for battery powered as a decoupling cap, low leakage.

Choose a cap with voltage 3x to 4x of input voltage.

MLCC or tantalum caps ?

You can also go for the TI Bq25570 which has support to solar Panels, Thermal and Piezo Electric Generators and available to buy everywhere !

Hi
According to wiki, using authentication prevent from delayed replay attack, but what about using only rfm69 hardware encryption, Isn't safe ?

Regards

The problem is within the bpi SPI implementaion.
I once tried almost everything to make it work but no success.
I advice you to switched to a serial gateway as a more robust installation.
