no change in set tx power

[Btje1977]

bool setTxPower(int txPower); was used and there is no change in power.

@Btje1977 please share a minimal sketch to reproduce, and what board/chip set you are using.

Hi. I'm trying to develop a bluetooth controlled automatic irrigation control. However, I have the same problem as Btje1977 ... when I call setTxPower there is no change in power. In my case I tried 2 generic Nrf51822 chips. Specifically, these 2 models: https://goo.gl/JJGUQ5 and https://goo.gl/hPi23D. I do not know if I misunderstood the setTxPower call method or missing something in my basic code: `

include

include

// define pins for nRF51822

define BLE_REQ -1

define BLE_RDY -1

define BLE_RST -1

define pin_valve 30

define pin_ledconnected 8

static int state = 0; int counter = 0; int wateringPower = -12;

BLEPeripheral wateringdevice = BLEPeripheral(BLE_REQ, BLE_RDY, BLE_RST); BLEService irrigationService = BLEService("19b10000e8f2537e4f6cd104768a1214"); BLEDescriptor valvedescriptor = BLEDescriptor("2901", "valve state"); BLEIntCharacteristic switchstatevalve = BLEIntCharacteristic("19b10001e8f2537e4f6cd104768a1214", BLERead | BLEWrite); BLERemoteService remoteGenericAttributeService = BLERemoteService("1800"); BLERemoteCharacteristic remoteDeviceNameCharacteristic = BLERemoteCharacteristic("2a00", BLERead);

void setup() { Serial.begin(9600);

if defined (__AVR_ATmega32U4__)

delay(5000);

endif

pinMode(pin_valve, OUTPUT); pinMode(pin_ledconnected, OUTPUT);

wateringdevice.setLocalName("wateringdevice 0001"); wateringdevice.setAdvertisedServiceUuid(irrigationService.uuid()); wateringdevice.setDeviceName("DevWaterx041"); wateringdevice.setAppearance(0x0080); wateringdevice.addRemoteAttribute(remoteGenericAttributeService); wateringdevice.addRemoteAttribute(remoteDeviceNameCharacteristic); wateringdevice.addAttribute(irrigationService); wateringdevice.addAttribute(switchstatevalve); wateringdevice.addAttribute(valvedescriptor); wateringdevice.begin(); wateringdevice.setTxPower(wateringPower); }

void loop() {

BLECentral central = wateringdevice.central(); if (central) { while (central.connected()) { digitalWrite(pin_ledconnected, HIGH); // central still connected to peripheral if (switchstatevalve.written()) { state = switchstatevalve.value(); } } } watering_control (); }

void watering_control() { digitalWrite(pin_ledconnected, LOW); switch (state) { case 0: digitalWrite(pin_valve, LOW); break; case 1: digitalWrite(pin_valve, HIGH); break; case 2: if (counter < 3) { digitalWrite(pin_valve, HIGH); delay (10000); digitalWrite(pin_valve, LOW); delay (20000); } else { digitalWrite(pin_valve, LOW); counter = 0; state = 0; } counter++; break; } } ` Where am I going wrong? Any help at all would be appreciated!

Sorry for the delay:

// Import libraries (BLEPeripheral depends on SPI)

include

include

// define pins (varies per shield/board)

define BLE_REQ 10

define BLE_RDY 2

define BLE_RST 9

boolean ledState=LOW;

// create peripheral instance, see pinouts above BLEPeripheral blePeripheral = BLEPeripheral(BLE_REQ, BLE_RDY, BLE_RST); // create service BLEService ledService = BLEService("19b10000e8f2537e4f6cd104768a1214"); // create switch characteristic BLECharCharacteristic switchCharacteristic = BLECharCharacteristic("19b10001e8f2537e4f6cd104768a1214", BLERead | BLEWrite);

void setup() { Serial.begin(9600);

// set LED pin to output mode pinMode(PIN_LED1,OUTPUT); pinMode(PIN_LED2,OUTPUT);

// set advertised local name blePeripheral.setLocalName("F1ST");

// blePeripheral.addAttribute(ledService); blePeripheral.addAttribute(switchCharacteristic);

// begin initialization blePeripheral.begin();

//Different settings blePeripheral.setTxPower(-10); blePeripheral.setDeviceName("ServoTimer");

}

void loop() {

//Bluetooth handeling BLECentral central = blePeripheral.central();

//Alive led digitalWrite(PIN_LED1, HIGH);
delay(100);
digitalWrite(PIN_LED1, LOW);
delay(10000); }

@Btje1977 what board are you using?

[sandeepmistry]

Closing for now due to lack of activity.

Hi, I am facing the same issue as above. The board that I am using is Generic nRF51822. I'm setting the Tx Power as -30 but still do not see any change being reflected. Any reason for that/

Thank you!
