Connect to more than 4 peripherals simultaneously

General

Hi all,

  • I try to connect to more than 4 BLE peripherals simultaneously.
  • I set the parameters ‘CONFIG_BTDM_CONTROLLER_BLE_MAX_CONN’ and ‘CONFIG_BTDM_CONTROLLER_BLE_MAX_CONN_EFF’ both to 5 in the yml-file
  • Connecting to the 5th peripheral, I see the message “BT_APPL: No resources to open a new connection”

Has anybody an idea, where this error message comes from and how to solve this problem?

Thanks and kind regards
Rolf

You seem to be using the ESP32 as a client, connecting to several servers.
Mongoose-OS is mostly a wrapper for the ESP-IDF here, and a quick search for the first of your macros points to this page in Espressif’s documentation.
