Sending data and receiving it in wrong format

NB-IoT
#1

When i send data using the command
AT+NMGS=6,“4B414D49454c”
the API call deviceDataHistory reports the raw data as
“rawData”:“S0FNSUVM”

Does anyone have any idea that the relation might be and why the data is messed up ?

Thanks

“deviceDataHistoryDTOs”: [
{
“deviceId”: “7c3e60c5-90e3-4ad8-8a0a-094b02d0239d”,
“gatewayId”: “7c3e60c5-90e3-4ad8-8a0a-094b02d0239d”,
“appId”: “ZvwWrt3i_ByYgWpz6fW_FhMStwsa”,
“serviceId”: “RawData”,
“data”: {
“rawData”: “S0FNSUVM”
},
“timestamp”: “20180322T143910Z”
},

Hi @Kamiel_Straatman,

4B414D49454c is the same as S0FNSUVM
S0FNSUVM this is BASE64, you can decode this back to hexadecimal

Kind regards,
Jan

Hi Jan

Thanks for the (correct) answer. I dis some experimenting and found also that the data is base64 coded while being forwarded by the CDP platform.

On Unix:
echo CVIQwgPoAAAAAAAAAAA | base64 --decode | hexdump
0000000 09 52 10 c2 03 e8 00 00 00 00 00 00

Thanks
