User-owned AT commands

#1

I would like to add custom AT command to my Heltec Cube Cell module,
can someone provide details how to develop/add custom AT commands?

#2

Try this

bool checkUserAt(char *cmd, char *content)
{
if (strcmp(cmd, “BATTERY”) == 0)
{
if (content[0] == ‘?’)
{
uint16_t BatteryVoltage = getBatteryVoltage();
Serial.print("+BATTERY=");
Serial.print(BatteryVoltage);
Serial.println();
}
return true;
}
if (strcmp(cmd, “LED”) == 0)
{
if (content[0] == ‘?’)
{
Serial.print("+LED=");
Serial.print(LoraWan_RGB);
Serial.println();
}
return true;
}
return false;
}

When cube cell is in low power mode it give following error for command,
using “LoRaWan_downlinkdatahandle” example

DR=1
[00]ASR is Waked,LowPower Mode Stopped
DR=1
+ERROR: error input format

so, is there anyway to use your code with low power mode? how to change low power mode to normal mode?

You have to wake up the cubecell before you can type in at commands.

The first command will wake the cubecell after that all command will function until the cubecell will go to sleep again

i’ve remove the LoRaWAN.sleep() from the calling but device returns the same error

DR=1
[00]ASR is Waked,LowPower Mode Stopped
DR=1
+ERROR: error input format

Dont remove the sleep.

Just type in the commands two times in your serial console
