Blackfin high speed USB host with Hologram Dash


#1

I have managed to send data from Hologram dash to Hologram Cloud using Raspberry Pi. Now, I am trying to do the same with Blackfin controller made by Analog Device.

Through the Analog Device Blackfin controller, I manage to send/receive AT command/response to Hologram Dash such as
AT — OK
ATE0 ---- OK
AT+CMEE=2 — OK
AT+CPIN? — +CPIN:READY OK
AT+CTZU=1---- OK
AT+CTZR=1— OK
AT+CPMS=’‘ME’’,“ME”,“ME” — +CPMS:0,300,0,300,0,300 OK
…and so on

I use AT+USOCO=0,“cloudsocket.hologram.io”,9999 to connect hologram.
AT+UDCONF=1,1 to enable the socket.
To send data, I use
AT+USOWR=0,3,’’“AAA”, where 0 represents socket number, 3 represents data length and “ÄAA” represents data.

I do not get any response back from Hologram Dash. What else do I need to put in data so that I can send data to Hologram Cloud?

Thanks in advance!
