For HM-10 / HM-11:

For the nRF51822:

The nRF51822 seems to require less overall power than the HM-10 / HM-11.

The biggest reason is that nRF51822 is a mega-overkill for a keyboard. It's a 32bit ARM microcontroller, with 128KB or 256KB of flash and 16KB of RAM. My first two personal computers were less powerful than that MCU.

CC2541 Bluetooth V4.0 HM-11 BLE Module is only $12.90.

Ok, good to hear.

Not sure if you've seen this for snooping nRF24 packets off the air:

And the earlier post about promiscuous wireless / snooping ms keyboard traffic:

Kile,

Wow, your wireless version looks great.

But is there some reason why you're not using the nRF51822 (and Bluetooth LE, HID over GATT) rather than the older NRF24LE1 ???
