Hi, I read others cases obout the problem to send more than 20 bytes trhough BLE and add on my prj.conf the next three lines:
#GATT_CLIENT needed for requesting ATT_MTU update CONFIG_BT_GATT_CLIENT=y #PHY update needed for updating PHY request CONFIG_BT_USER_PHY_UPDATE=y #For data length update CONFIG_BT_USER_DATA_LEN_UPDATE=y
This is the entire prj.conf:
# Drivers selection CONFIG_LOG=n CONFIG_SERIAL=y CONFIG_BOOT_BANNER=n CONFIG_PINCTRL=y CONFIG_GPIO=y CONFIG_ADC=y CONFIG_ADC_ASYNC=y CONFIG_ADC_NRFX_SAADC=y CONFIG_I2C=y CONFIG_NRFX_TWIM1=y CONFIG_FLASH=y CONFIG_SPI=y CONFIG_SOC_NRF52832_ALLOW_SPIM_DESPITE_PAN_58=y CONFIG_NRFX_SPIM0=y CONFIG_NRFX_SPIM2=y CONFIG_FLASH_PAGE_LAYOUT=y CONFIG_MPU_ALLOW_FLASH_WRITE=y CONFIG_SOC_FLASH_NRF_EMULATE_ONE_BYTE_WRITE_ACCESS=y CONFIG_REBOOT=y # Stacks and heaps # This configuration reserve 20K of RAM to HEAP, this project only has 64K # and all the code is the 98% of the RAM so we can not declare so much heap CONFIG_HEAP_MEM_POOL_SIZE= 8000 #CONFIG_HEAP_MEM_POOL_SIZE= 6144 CONFIG_MAIN_STACK_SIZE=1024 CONFIG_SYSTEM_WORKQUEUE_STACK_SIZE=4096 #CONFIG_NET_TX_STACK_SIZE=512 #ONFIG_NET_RX_STACK_SIZE=512 # CONFIG_NET_MGMT_EVENT_STACK_SIZE=2048 # BLE configuration CONFIG_BT=y CONFIG_SETTINGS=y CONFIG_BT_PERIPHERAL=y CONFIG_BT_GATT_DYNAMIC_DB=y CONFIG_BT_DEVICE_NAME="BLE Device" #GATT_CLIENT needed for requesting ATT_MTU update CONFIG_BT_GATT_CLIENT=y #PHY update needed for updating PHY request CONFIG_BT_USER_PHY_UPDATE=y #For data length update CONFIG_BT_USER_DATA_LEN_UPDATE=y CONFIG_BT_L2CAP_TX_MTU=247 CONFIG_BT_BUF_ACL_TX_SIZE=251 CONFIG_BT_BUF_ACL_RX_SIZE=251 # Debug configuration CONFIG_DEBUG=y CONFIG_DEBUG_OPTIMIZATIONS=n CONFIG_DEBUG_THREAD_INFO=y
Butr when I try to send more than 20 bytes doesn´t receibe anithing.
Could any say me that other parameters could I chech?
I use nRf52832 SDK: 2.5.0
Thanks in advance.
Regards
