The values are stored in the RTC and would only be affected by removing power. Resetting the CPU or Flash will have no affect.

I can reproduce the error if I choose mbed-os-5.15.1 revision

We changed repos as the old one had mbed5 in the name.

Indeed a protocol must be implemented by both sides to be useful.

The 4.0.0 release has redundant config and session storage saved apart from the file system. A corrupted file system will no longer cause loss of credentials, key or counters needed to join the network.

[Jason Reiss]

Also with FOTA enabled the Dot will send GPS Time request MAC commands to sync the time. This can affect some network servers that do not have support for the GPS Time command.

[Jason Reiss]

The Dot 4.0.0 includes support for LoRaWAN 1.0.4. This implements join nonce counter validation by default that verifies that the Join Accept nonce value has incremented from the last received value. Some network servers, such as TTN community, may return random nonce values that can cause the join to fail with this validation enabled.

This behavior can be disabled with this function if needed. Or with AT+JNV=0 in AT firmware.

        /**
         * Enable/disable Join Nonce validation for App Nonce in Join Accept
         * Default is enabled
         */
        int32_t setJoinNonceValidation(bool enable);
        bool getJoinNonceValidation();

mPower 5.2.1 or greater is compatible and implements the join nonce counter, older versions provide random nonce values.

You should switch to root before issuing the command. The root user will be reset when the command is issued and sudo cannot be used afterwards.

$ sudo -s
# reset-defaults
# shutdown -r now

The API could also be used with the restore_defaults or restore_factory commands. The Conduit will reboot after the command is issued.

Commands

$ curl -X POST 127.0.0.1/api/command/restore_defaults -H "content-type: application/json" --data ""

What is the reason for lost uplinks?

[Jason Reiss]

A “region” setting may be needed.

https://doc.sm.tc/station/tcproto.html?highlight=region

“region”: “AS923JP”

https://github.com/lorabasics/basicstation/blob/817e6e1e7f0c3affce078bac7b060ba675043664/src/s2e.c

There should be a region log message

LOG(MOD_S2E|INFO, “Configuring for region: %s%s — %F..%F”,

[Jason Reiss]

With two cards installed this can be done in packet forwarder mode to remote servers.

If you are using the embedded network server this mode of operation is not supported.

[Jason Reiss]

The mosquitto_pub and mosquitto_sub commands are helpful when working with MQTT.

$ mosquitto_sub -v -t lora/#

$ moquitto_pub -t lora/0011223344556677/down -m {“data”:”AQ==”}

[Jason Reiss]

These commands are used by the UI to get the list of packets received.

$ lora-query -x packet list json

$ lora-query -x packet up json

What results are you see to make you say it does not work?

If you do not have creds for the device, how are authorized to make changes at all?

[Jason Reiss]

How is that more simple than direct json data as requested?

/var/run/lora/lora-network-server.db is the active file. /var/config/lora is a periodic backup.

[Jason Reiss]

Can you share an example of the command you are trying to use?

Realtime data can be obtained with an MQTT client application.

See an example here.

What version of mPower/AEP are you using?

Disable "enableStrictCounterValidation"

[Jason Reiss]

Is the device connected via ABP where the session DevAddr, NwkSKey and AppSKey are set?
Perhaps the device resets the FCNT to 0 when reset. The network server will reject previously received FCNT values to protect from packets being replayed.

Best practice would be for the device to save the last used FCNT and resume the session to keep replay protection.

Or you can choose the Disable Strict Counter option under the Network Server Testing section of the LoRaWAN > Network Settings page to allow a device to reset the FCNT. Click Save and Apply after submitting the changes to restart the Network Server.

It appears that the mtcap update file is not the correct file.

Received packet data will be stored in the Network Server database and published to the local MQTT broker.

The lora-query utility can be used to retrieve the packet data from the Network Server.

How are you configuring the gateway? Through the UI or file system?
Does the gateway have TTN software installed?

Through the UI the Packet Forwarder Manual Configuration would be needed to provide the global_conf.json file with “fake_gps” and “ref_*” fields.

[Jason Reiss]

Here are the end-points for the API.

I usually use a browser to inspect the calls made by the UI for JSON examples of API calls.

The frequencies used to setup the Channel Plan are located here.
https://os.mbed.com/teams/MultiTech/code/libmDot-dev-mbed5-deprecated//file/0f5a742a08cd/Lora.h/

    const uint32_t EU868_MILLI_1_FREQ_MIN = 868700000;
    const uint32_t EU868_MILLI_1_FREQ_MAX = 869200000;

And used in ChannelPlan_EU868.cpp to setup the duty-cycle band with a max power on lines 201-208.

    band.Index++;
    band.FrequencyMin = EU868_MILLI_1_FREQ_MIN;
    band.FrequencyMax = EU868_MILLI_1_FREQ_MAX;
    band.PowerMax = 14;
    band.TimeOffEnd = 0;
    band.DutyCycle = 1000;
 
    AddDutyBand(-1, band);

The PowerMax is used in SetTxConfig to limit the max power allowed on the channels within the defined band.

Let me know if that helps.

Can you provide a link to the file you are trying to edit?

Looking at the packet_sent event the packet_forwarder “powe” field is set to 13 for 868.3 MHz
+16 dBm EIRP minus the +3 dBi antenna gain.

Data should be base64 encoded

Also add the header option

What does myXdotbat.getBatteryLevel() do?
What value is it returning?
Does it change if you fix the value returned by getBatteryLevel() to 128?
