Hi, i'm doing some experiments with MIWI demo board (http://ww1.microchip.com/downloads/en/DeviceDoc/70687A.pdf).
I try to substitute the MRF24J40MA module with the stronger MRF24J40MD in order to increase signal strenght. Apparently the modules are compatible both in hardware both in software, but with the MD modules inside the demo boards doesn't communicate. My work is based on Microchip sample code ("C:\microchip_solutions_v2013-06-15\MiWi DE Demo\MiWi Demo Kit" when installed on pc). I try to change some hardware defines (e.g #define MRF24J40MB / MRF24J40MC) but unsuccessfull.
An other information: when i substituted only one module (on the other side still MA is mounted) communication happens, when have changed also the other side communication fails.
I tried also to mount the MC module (with external antenna) but always unsuccessfull.
If you suggest me the right solution to let the demoboard work with the MD and MC modules you win the payment.
I attach the MPLAB...
