[Shimmer-users] How to work with CoAP in Shimmer?

[Ashis Kumar Bhowmik]

Hello everyone,
I am a newbie to Shimmer. I want to implement CoAP in Shimmer sensor. I
want to program sensor as CoAP server, and a cellphone or computer to work
as CoAP client.

Can anyone help me on this?
How do I program CoAP server firmware on Shimmer?
How can I connect cellphone (android) with the Shimmer Sensor to access
CoAP server?

Thanks in advance
Ashis

Dear Shimmer community,

I have a question concerning the calibration of Shimmer 3 using SD firmware.

I have been using the Bluetooth firmware and the calibration with 'Shimmer 9DOF Calibration Application' works well.
However, I do not know how to store this calibration for further use of the Shimmer3 with the SD firmware.

The manual states:
'If you reprogram the Shimmer with any firmware then the stored calibration parameters will be erased from the Shimmer memory.
Of course, I could save the parameters to a file but how can I reload the parameters to the Shimmer internal memory without using the Bluetooth firmware? At Shimmer2 there was the ‚calibparams‘ file on the SD card but using Shimmer3, all parameters are stored on the internal memory.


I tried different options but always evaluated that the Shimmer3 uses the DEFAULT calibration parameters whenever I use the SD firmware. Did I do something wrong or is there no calibrated SD firmware function?



Thanks for your help,
Ben
