I just bought a couple of HM-TRP 868GHz Hope modules and I would like to make a telemetry system.
I have been loking for the information in this 3DR part of the forum but I think a bit dumb I couldn´t find the information.
I just try to use the modules as they com from the factory.
Y make two test boards and one of them I conected to a FTDI
I conected this way
FTDI Module
VCC 3,3V regulator VCC
GND GND
TX Rx
Rx Tx
DTR NONE
CTS NONE
I start from changing the baud rate with the AA commands
I have send some AA sentences from a Hyperterminal Program connected @ 9600bps with the Com port (USB)
I type the sentence
AA FA C3 00 00 E1 00 to change the wireless baud rate (57600) and the module record this parameter
When I type the nest sentence,
AA FA C3 00 00 E1 00 to change the UART baud rate (57600) after I send the sentence I could not talk to the module anymore.
I did a new connection with 57600 baud rate but it does not answer the correct answers. I have answers but it looks like is in another baud rate.
I don´t know how to go back and star from the beginning.
I just thought to star changing the bootloader and the firmware to conect them to the 3DR program.
Can anybody tell me something about how to change the boot and the FW.
Thanks a lot.
Alberto

Even if it's fall of 2014, I'm still using LPT programmer :-)
I have not tried that, but Arduino is so cheap that it's worth to try :-)
Exactly.
I've never used FlashLoad Lite.
Try this, it works fine for me: http://silabs.org.ua/sp_en.htm#SP
If OlliW app can program any hex - use something from my post:
http://diydrones.com/forum/topics/hm-trp-868-sik-software-link-prob...
Remember - use correct one for your frequency range.
Try FlashLoadLite http://dilogic.hr/Downloads/Files/FLLiteSetup.zip , I'm not sure if it can handle Arduino C2 programmer.
Other way is to use Slabprog with FlashBlaster2, I've buid this one:

You're welcome :-)
I'm not able to reply below.
Should work if you'll have software supporting it.
Hello Marcin,
I have been looking for the programmer but in Spain is out of stock, I think I can build as you did my own paralel prot programmer.
but I have a doubt (a lot actually)
In the schematic I can see several components called 100E , I don´t know what component is this I can imagine is a ressistor of 100 Ohmn but I am not sure (now you can see my electronics level)
I think I need two
74HC125N DIP14
Is any different betwin 74HC125 and the 74HC125D
If mine doen´t work. I can buy one like this.
Also I have seen this programmer
http://www.ebay.es/itm/Xilinx-JTAG-Parallel-Cable-III-FPGA-CPLD-pro...
Do you think I can use it. I think it is OK for the Module.
For the program to flash the IC I have seen the flashload lite
Am I in the right way??
Thanks
Alberto
You have to upload SiK firmware to modules using proper programmer.
Take a look at my post at Polish forum (use Google Translator): http://rc-fpv.pl/viewtopic.php?t=8011
Here you can find compiled firmware and bootloader files: http://diydrones.com/forum/topics/hm-trp-868-sik-software-link-prob....
