Node with ESP8266 and RFM95W

What is “almost no current”? would be good to know for battery life purposes.

hi ,

we try to use a RFM9x LORA radio with an ESP D1 mini .we have big problem with wiring the module . in the monitor we see that messages are normally send . but we don t have anything in the data console of ttn .
as you can see we have this in the monitor :lorawan

i think the problem is the " unknown event" that happened at each time .

for our pin mapping we do this ;
// Pin mapping
const lmic_pinmap lmic_pins = {
.nss = 15,
.rxtx = LMIC_UNUSED_PIN,
.rst = LMIC_UNUSED_PIN,
.dio = {4, 5, LMIC_UNUSED_PIN},
};

we don’t know if it’s correct or not .

see How should I wire an RFM95 to an ESP8266/WeMos D1 mini?

D8 (GPIO15) -> NSS
D5 (GPIO4)->SCK
D7 (GPIO13)->MOSI
D6 (GPIO12)->MISO
D1(GPIO5)->DIO 0
D2(GPIO4)->DIO 1

const lmic_pinmap lmic_pins = {
.nss = 15,
.rxtx = LMIC_UNUSED_PIN,
.rst = LMIC_UNUSED_PIN,
.dio = {4, 5, LMIC_UNUSED_PIN},
};

seems ok … check again :wink:

we do , but no sucess .
i think the wiring is different for our module because we don’t have just lora module but wa have something like this ;
lora
do you tkink this type of module work same as the green card ?
what can be the unknown event ?
