How can I write characteristic values int or float from central

[Arepa]

Hi I am using the SDK 12 and I am doing some test using the experimiental_app_ble_blinky central and peripheral parts.

I see in this example it use boolean values to indicate estatus.

If I modify the size the characteristics how can I write(central side) values int or float in case I want to sent 6 characters.

err_code = ble_lbs_led_status_send(&m_ble_lbs_c,button_action);

button_action allow just boolean type I cant see where change it

thanks

Where did you modified the size? You have to modify it when you add the characteristic on the peripheral/server. In addition you have to change the ble_lbs_led_status_send() function on the central/client.

I edited the size in the peripheral side and in the central(client) side I did the following:

enter code herep_msg->req.write_req.gattc_value[0]        = status;		
p_msg->req.write_req.gattc_value[1]        = 0x01;
p_msg->req.write_req.gattc_value[2]        = 0x02;

for testing so after this change I am not able to receive in the peripheral the written cmd. and after this when I tried to notificate to the central I got fatal error in the peripheral side

I think it is a issue with the cccd because it also use the gattc_value[0] and [1]

Solved

The error was related to the value atp_msg->req.write_req.gattc_params.len = WRITE_MESSAGE_LENGTH;

Everything is working now?
