Re: How to increase MTU size on GATT - Server

I'm running into a weird problem where in the GATT server, after a connection is established the MTU request has been somehow canceled. I get this: I (12243) GATTS: ESP_GATTS_CONNECT_EVT, conn_id 0, remote 63:61:78:a6:49:b4 Then: I (12481) GATTS: ESP_GATTS_MTU_EVT, MTU 80 for conn_id 1 So far so goo...

Re: Bluetooth TX Power

It seems like the radio is configured to the minimum output power, index 0 /* adv tx power level */ #define BTM_BLE_ADV_TX_POWER_MIN 0 /* minimum tx power */ #define BTM_BLE_ADV_TX_POWER_LOW 1 /* low tx power */ #define BTM_BLE_ADV_TX_POWER_MID 2 /* middle tx power */ #define BTM_BLE_ADV_TX_POWER_UP...

Please tell us how to change the RF transmit power when using BLE.
Thanks

radio TX and RX indicatore

Guys, Is it possible to get a notification when the transmitter is creating microwaves and when the receiver is active? Reason for that is to be able to monitor when high power is being used, as PA and LNA are pretty power hungry. It would be nice to link those indicators to a GPIO and to LEDs to sh...
