+Notes:
+ - RX output will match the eSky standard TAER independently of the input configuration AETR, RETA... unless on OpenTX 2.3.3+ you use the "Disable channel mapping" feature on the GUI.
+ - To run this protocol you need both CC2500 and NRF24L01 to be enabled for code reasons, only the CC2500 is really used.

+Telemetry: RSSI is equal to TX_LQI which indicates how well the TX receives the RX (0-100%). A1 voltage should indicate the numbers of life remaining (not tested). A2 is giving the model status using a bit mask: 0x80=flying, 0x08=taking off, 0x04=landing, 0x00=landed/crashed

+This protocol is known to be problematic because it's using the xn297L emulation with a transmission speed of 250kbps therefore it doesn't work very well with every modules, this is an hardware issue with the accuracy of the components.
+
+If the model does not respond well to inputs or hard to bind, you can try to switch the emulation from the default NRF24L01 RF component to the CC2500 by using an option value (freq tuning) different from 0. Option in this case is used for fine frequency tuning like any CC2500 protocols so check the [Frequency Tuning page](/docs/Frequency_Tuning.md).

A real finetune value of 127 means, the frequency of module is out of range and the module should be replaced. This way the clone mode should not get unwanted active by a module with a frequency drift arround 63.	2020-04-10 19:01:01 +02:00
