Hi there!
I am Pranav, from India.
I just went through your project description, and got the idea of what is required.
I believe you want custom software development for both the master and the slave boards. Please correct me if I am wrong.
My bid includes the firmware for both as deliverables at the end of the project.
I would be requiring two CC2540 based modules and a AM1808 to commence the work and a maximum of 7 days for the firmware development after I receive the hardware.
In addition I would require a prepaid milestone of USD50 before accepting the project as a security since you do not have any reviews yet and there are many people here that like to get their work done for free. This amount of USD50 will be adjusted in the final project payment.
Obviously, a detailed technical specification would be helpful from your side, describing in detail the functionality required in the project. It would help us create a layout for the milestones.
I am open to suggestions and you can get in touch with me here on FL for more details.
With warm regards,
Pranav
