Hello again,

I have already found a solution. NodeRed LORA input node is configurable regarding to the received data type (did not know). Data type is either UTF-8 or Bytes. After I set data type to Bytes everything seems to work properly.

Have a nice day.

Best regards,

Hello Peter,

yes I do. When var payloadRawData = new Buffer(msg.payload, 'base64'); is used the attempts to convert payloadRawData to string

msg.payload = payloadRawData[0].toString(16) + payloadRawData[1].toString(16) + payloadRawData[2].toString(16);

returns error TypeError: Cannot call method ‘toString’ of undefined.

I am not sure but I think that NodeRed msg.payload is not base64 encoded. The important information I need to know to solve this issue is how the LoRa received packet is proccessed before data is visible in the NodeRed envoronment (whole chain). Is it possible to send me this information?

One more note. Bassically every byte above the scope of ASCCI table (0x00 – 0x7F) is received wrong in the NodeRed.

Thank you.

Best regards,
Radim Malinowski

Hi Steve,

thank you for your advices. Everything works now. I misunderstood term MiniSIM card and I used MicroSIM instead. Sorry for troubles.

Have a nice day and whole new year.

Hi Steve,

first of all thank you for such a quick reply.

Serial number: 18814853

I read SIM card installing guide before I insert SIM card into Conduit therefore orientation is correct. When SIM card wasn´t inserted properely an error message showed up in Conduit GUI. Now I don´t see any error message.
