I bought some of these to implement in a project, the support is pretty shabby and see no one on the internet using these to workout in their project!, I have the soldered joints working well as I get ,the following:
HUM-900-PRO v1.0.0 (C) 2014 Linx Technologies Inc. All rights reserved.
now, I have 2 modules working and spitting out the same when I start the module and if I reset them, meaning the joints are well formed.
(functioning of the device, Pulling the POWER_DOWN high and pulling the CMD high and sending byte data over Arduino UART should transmit the data given the conditions like 64byte default overflow register overflows and send the stuff over wireless! (there are other 3 ways but Im just using this for the time being))
One also needs to pull CMD line down on the HUMpro to make it know that it's actually a CMD coming and not data bytes coming in that the user wants to transmit wirelessly.
I cant get it to work at all! I should receive an ACK (0x06 if its ok ) NACK (0x15 its not ok)
tried sending FF 03 FE 02 to read a register less than 0x80 index but doesnt work, also tried various flavors like:
0xFF 0x03 0xFE 0x02 & 0xFF0x030xFE0x02 (with spaces without spaces Blah! Blah! various trials! but couldnt get it to work at all!)
Can ANybody dig into this and guide me where its not working?
I tried to attach the Data guide but due to upload limit that couldn't happen ,please have the link to it : Datasheet CUM Dataguide
