Example "LoRaWan_OnBoardGPS_Air530.ino" stops working after some time

[schroepfer]

Board: CubeCell HTCC-AB02S GPS Version: 1.4.0 Example: LoRaWan_OnBoardGPS_Air530 > https://github.com/HelTecAutomation/CubeCell-Arduino/tree/master/libraries/LoRa/examples/LoRaWAN/LoRaWAN_Sensors/LoRaWan_OnBoardGPS_Air530 This example stops working after ca. 5 uplinks to TTN.

This seems to be the same error as issue #230 "GPS example sketch stuck after a couple of iterations".

Addendum: the software works longer with 1.3.0 ! It seems, that the error comes partly from here.

Same problem here....

yes,GPS.begin -> serial-begin : malloc(buf),no free(buf),change to global variable or serial-end :free(buf)

this fix does not work for me, the example still stops working after 12-20 hours...

Exactly! :-( I give up with this board....

In case anyone is still having this problem, in PlatformIO the solution is to change the platform in the platformio.ini file. If you choose the Cubecell GPS board when starting a project it will default to "platform = asrmicro650x". This platform is deprecated and must be manually changed to "platform = heltec-cubecell". Once this is done the GPS functionality will work correctly.

Thanks! I'm not so confirm in PlatformIO. I don't know, where to define the build-flags:

`/LoraWan region, select in arduino IDE tools/ LoRaMacRegion_t loraWanRegion = ACTIVE_REGION;

/LoraWan Class, Class A and Class C are supported/ DeviceClass_t loraWanClass = LORAWAN_CLASS;

/the application data transmission duty cycle. value in [ms]./ uint32_t appTxDutyCycle = 180 1000; / Should be 180 seconds / /OTAA or ABP*/ bool overTheAirActivation = LORAWAN_NETMODE;

/ADR enable/ bool loraWanAdr = LORAWAN_ADR;

/ set LORAWAN_Net_Reserve ON, the node could save the network info to flash, when node reset not need to join again / bool keepNet = LORAWAN_NET_RESERVE;

/ Indicates if the node is sending confirmed or unconfirmed messages / bool isTxConfirmed = LORAWAN_UPLINKMODE;`

Please can you post your platform.ini ?

This is all I have in my platformio.ini

; PlatformIO Project Configuration File ; ; Build options: build flags, source filter ; Upload options: custom upload port, speed and extra flags ; Library options: dependencies, extra library storages ; Advanced options: extra scripting ; ; Please visit documentation for the other options and examples ; https://docs.platformio.org/page/projectconf.html

[env:cubecell_gps] platform = heltec-cubecell board = cubecell_gps monitor_speed = 115200 framework = arduino

I found it. Without this build flags PlatformIO can not compile.

Now the software compiles, but the cubecell only connect once to TTN and then stops. :-(

`[env:cubecell_gps] platform = heltec-cubecell board = cubecell_gps framework = arduino
