@lood29 When I use TTGO LORA as a dummy sensor (Node 10 in the above log) it always works without any nacks.

The NACK only appears when I connect my own sensor (Node 140 in the log above).

So Scenario 1
Dummy sensor (TTGO LORA) <-> MQTT gateway (TTGO LORA) -> Works

Scenario 2
My sensor <-> MQTT gateway (TTGO LORA) -> NACK in the Gateway.

Hi

Im trying to setup a temperature sensor that should be placed at my jetty, 350 meters from my house. So I have chosen RFM95 as my radio, an E-ink display to show the temperature but I have some struggle to this setup. Need some debug help.

As the controller I have a TTGO LORA.

I have two of the TTGO LORA, One gateway and one debug sensor, so I can verify that thoose are working with mysensors but when I add my custom sensor I receives a lot of !RFM95:SWR:NACK from the Gateway.

And here I can see that the gateway recieves data from sensor 140 but can't ack :(

Can someone please help me?

@electrik A ticket is raised quite long time ago, https://github.com/mysensors/MySensors/issues/1376

No I have no idea. For me it seems to work.

Currently I don't have any sensors conncted so its hard to see if it works.

@DenisJ I have the same problem. Works with

#define MY_GATEWAY_ESP32

but with

#define MY_GATEWAY_ESP32
#define MY_GATEWAY_MQTT_CLIENT

it dosen't. But when I changed the delay to 3000

bool gatewayTransportConnect(void)
{
#if defined(MY_GATEWAY_ESP8266) || defined(MY_GATEWAY_ESP32)
	if (WiFi.status() != WL_CONNECTED) {
		GATEWAY_DEBUG(PSTR("GWT:TPC:CONNECTING...\n"));
		delay(3000); // Was 1000
		return false;
	}
	GATEWAY_DEBUG(PSTR("GWT:TPC:IP=%s\n"), WiFi.localIP().toString().c_str());

in MyGatewayTransportMQTTClient.cpp then it started to work! :)

@mrussi I am also interested in using an esp32 with lora as the gateway. Did you make it work?

I planning to buy, https://www.botnroll.com/en/esp/2979-esp32-wifi-bluetooth-lora-sx1278-433mhz-with-0-96-oled-display.html

I have been trying @nagelc code with a lot of debug prints and I think that my device is stuck after

MyHwNRF5.cpp

inline void hwSleep(void)
{	CORE_DEBUG(PSTR("In hwSleep, 345\n"));
	__WFE();
	__SEV();
	__WFE();
	CORE_DEBUG(PSTR("In hwSleep, 351\n"));
}

int8_t hwSleep(uint32_t ms)
{
	hwSleepPrepare(ms);
	while (nrf5_rtc_event_triggered == false) {
		hwSleep();
	}
	CORE_DEBUG(PSTR("In hwSleep, 357\n"));
	hwSleepEnd(ms);
	return MY_WAKE_UP_BY_TIMER;
}

And I will not go to hwSleepEnd

11274 MCO:SLP:MS=5000,SMS=0,I1=255,M1=255,I2=255,M2=255
11280 TSF:TDI:TPD

11286 In hwSleepPrepare, 287
11289 In hwSleepPrepare,300

@nagelc Thanks will try

@nagelc can you use
MY_DEBUG_VERBOSE_NRF5_ESB

Do I need to add a bigger capacitor between gnd and +3?

I have a feeling that the

Wait()

Is the problem but haven't had time to investigate.

Someone that can help me?

Hi

I want to understand how the hwSPI works for the NRF52 and a RFM95 module.

I suppose that I can define more then one SPI interface in the file MyBoardNRF5.h so it looks like
SodaqMoja/SodaqCore-samd (should be updated to the NRF52 pins)

#ifdef ENABLE_SPI1
#define SPI_INTERFACES_COUNT 2
#else
#define SPI_INTERFACES_COUNT 1
#endif

// SPI
#define PIN_SPI_MISO         (42u)
#define PIN_SPI_SS           (43u)
#define PIN_SPI_MOSI         (44u)
#define PIN_SPI_SCK          (45u)

static const uint8_t MISO = PIN_SPI_MISO;
static const uint8_t SS   = PIN_SPI_SS ;
static const uint8_t SS_DFLASH  = PIN_SPI_SS ;
static const uint8_t MOSI = PIN_SPI_MOSI ;
static const uint8_t SCK  = PIN_SPI_SCK ;

// SPI1
#define PIN_SPI1_MISO        (53u)
#define PIN_SPI1_SS          (54u)
#define PIN_SPI1_MOSI        (55u)
#define PIN_SPI1_SCK         (56u)

static const uint8_t MISO1 = PIN_SPI1_MISO;
static const uint8_t SS1   = PIN_SPI1_SS;
static const uint8_t MOSI1 = PIN_SPI1_MOSI;
static const uint8_t SCK1  = PIN_SPI1_SCK;

But I don't get how I will init the second SPI bus and point it to the RFM95 module. Guessing it should be define RFM95_SPI SPI1 or something like that?

#if !defined(RFM95_SPI)
#define RFM95_SPI hwSPI //!< default SPI
#endif

@omemanti Well it seems to start working now... Hopefully it works :) Havn't restart the gateway in 2 weeks now

I have recently installed an Ebyte E73 as my gateway with a DHT22. The problem is that I need to restart the gateway every 2 days and I can't figure out why. Can someone help me?

/**
   The MySensors Arduino library handles the wireless radio link and protocol
   between your home built sensors/actuators and HA controller of choice.
   The sensors forms a self healing radio network with optional repeaters. Each
   repeater and gateway builds a routing tables in EEPROM which keeps track of the
   network topology allowing messages to be routed to nodes.

I have been able to use platformio for my project quite recently and still have some problems that I haven't had time to solve yet.

My platformio.ini for a NRF51832

[env:nrf51_dk]
platform = nordicnrf51
framework = arduino
board = rfduino
upload_protocol = stlink
board_build.f_cpu = 16000000L
build_flags = -DNRF51 -DMYBOARDNRF5 -I{build.path}

the only problem for my is that the flags

-DMYBOARDNRF5 -I{build.path}

dosen't work so the mynrf5board.h/c isn't read => I need to update the
vim ~/.platformio/packages/framework-arduinonordicnrf5/variants/Generic/variant.h myself.

@neverdie Sorry, im a bit confused.

If im are going to use the BT832 for a battery sensor do I need to connet a 32 khz crystal like you did on the 10+ years wireless PIR Sensor (on just one set of 3 AA's!) project? But you have also written:
@neverdie said in nRF5 action!:

@alowhum IIRC, the crystal oscillator is only required by Bluetooth. For everything else, the internal resonator is sufficient.

How much more current are used if the crystal is not connected?

Can I use P00/P01 as a data pin instead of using the crystal?

@neverdie Im guessing that the BT832 dosen't have the 32.768 khz crystal but the inductors?

The datasheet says

Standby current consumption is important for battery-powered product. We suggest adding a 32.768 kHz crystal 
and 2 capacitors as shown in the upper left corner of the evaluation board schematics. The 32MHz main clock 
won’t be active at idle state to save power.

Two inductors required for DCDC converter are inside BT832 module. You can enable DCDC to lower
power consumption.

@NeverDie How do I know which nRF52832 board I should use?

Does the CFsunbird-nRF52832 has the DC/DC inductors?
Or can I use nRF51822?

Want a cheap chip, easy to solder (Have a couple of Ebyte e-73 but they take some time to solder :( and if I understand correctly, the DC / DC inductors are missing?)

@monte But you solve your issue with the WT15822 board? Can you please share your sketch?

Is the range good of the WT15822 board?

I have started sketching to create a couple of new simple temp / hum sensors (WT15822, si7021 and cr2032) and want to know if I can use WT15822 before I order a pcb :)

Hi.

I have read https://devzone.nordicsemi.com/b/blog/posts/measuring-lithium-battery-voltage-with-nrf51 but which pin is VBG? p0.01 = adc?

Need to recalclulate the resistance for 2 aaa batteries.

@alowhum Can you clearify how to read MyBoardNRF5.h? Is PIN_AIN0 = p0.00?

What is the benift to use hwPinMode instead of using pinMode()?
