Possible error within the tune function regarding transmit power.

[czubri]

Step 1: What do you want?

There might be a wrong value within the standart TX Power Configuration inside the tune function.

Step 2: Describe your environment

• Arduino IDE version or Toolchain:
• dw1000 Library version: 0.9
• Arduino device: ESP32
• Used adapter board: selfmade

Step 3: Describe the problem

I might me wrong or there might be a good reason for this but it seems to be that there might be a wrong value within the tune function for the transmit power. For channel 5 with smart transmit power control and 64 Mhz pulse freq. the DW1000 Manual (Version 2.18 Page 107) suggests a Value of 0x25466788 but within the tune function the value for this case is set to 0x25456585. All the other values the libraray seems to match the suggestion so i was wondering about this. See DW1000.cpp line 651.

Affected file(s) or example(s):

DW1000.cpp line 651
DW1000 Manual (Version 2.18 Page 107)

Steps to reproduce:

not applicable

Observed Results:

did not test transmit power in this range

Expected Results:

wrong transmitpower possible

Relevant Code:

  } else if(_pulseFrequency == TX_PULSE_FREQ_64MHZ) {
			if(_smartPower) {
				writeValueToBytes(txpower, 0x25456585L, LEN_TX_POWER);
			} else {
				writeValueToBytes(txpower, 0x85858585L, LEN_TX_POWER);
			}
