Set Power Transmission JN5169 M00-02

[khactrung]

Hi all,

I need to increase the power transmission of JN5169.

I used the function eAppApiPlmeSet(PHY_PIB_ATTR_TX_POWER, PHY_PIB_TX_POWER_MAX) but not affected .

I'm using JN-SW-4170 sdk.

Coud you please help me ?

Khac Trung.

Hi Khac,

Could you please look at the next community post?

Hi Mario,

Yes, i've look at that community post, i set as bellow, but the power transmission seem not better:

u32JPT_Init(); /* initialise production test API */

bJPT_RadioInit(E_JPT_MODE_HIPOWER);

vJPT_RadioSetPower(5);

Thanks & Best Regards,

Hi Khac,

Where is the test range performed by the customer?

Here are a few parameters to take into account:

1) the modules configuration themselves to get the best link budget (max Tx power set)

2) the antenna ('gain/directivity', orientation)

3) the environment:

      a) boards have to be on none metal support at ~1/2m of the floor, 

      b) far of other radio interference (wifi, ...)

      c) empty area (without building,...)

 So, you would need to just call the below function in your application during startup. For example:

vAppApiSetHighPowerMode( APP_API_MODULE_HPM06, TRUE );‍

And then setting the appropriate Tx level using 

eAppApiPlmeSet(PHY_PIB_ATTR_TX_POWER, (uint32)(22));‍

Hi Mario,

I test it in the empty area room.

I configured as your guide, the power transmission improved:

vAppApiSetHighPowerMode( APP_API_MODULE_HPM06, TRUE );
eAppApiPlmeSet(PHY_PIB_ATTR_TX_POWER, (uint32)(22));

But i don't know which is the best value in the function eAppApiPlmeSet for max power transmission setting (10 dBm).

I read the JN-UG-3087 Peripherals doc, but i don't understand how to calculate.

Thanks & Best Regards,

Hi Khac,

Please look at the IEEE 802.15.4 Stack User Guide v2.6

3.8.1 Transmission Power Table 5

Hi Mario,

That doc said it used for JN516x M06, but my module is JN5169-001-M00 2.

Can it compatible ?

Thanks & Best Regards,

Hi Khac,

Just remember that you have a standard module, it is not a high power module.

 For JN5169 and JN517x, it is mapped to the nearest of 26 levels in the range -32 to +10 dBm

Hi Mario,

In earlier post, you said that call bellow function to set  the maximum power transmission:

eAppApiPlmeSet(PHY_PIB_ATTR_TX_POWER, (uint32)(22));

1. I don't understand how to map the 22 value to the dBm. Because of the table 5 said that "Power Level Mappings for JN516x Modules (except JN5169)". My module is JN5169-001-M00 2.

2. On the table 5, refer to the Standard-Power Modules column, value is 0. It mean that 0 dBm is maximum ? 

Thanks & Best Regards,

Hi Khac,

Firstly it is worth mentioning that our devices operate at their highest power by default there should only be a need to change the radio power settings to lower them.

1. I don't understand how to map the 22 value to the dBm. Because of the table 5 said that "Power Level Mappings for JN516x Modules (except JN5169)". My module is JN5169-001-M00 2.

And here it is for JN5169:
