Send data with sd_ble_gatts_hvx with custom length

Hi Elshat, 
How many bytes do you want to notify and how many byte you actually received ? 
As far as I know the maximum notification size is NRF_SDH_BLE_GATT_MAX_MTU_SIZE = 247. 
I would suggest to split your data into multiple notifications and you can think of using one extra byte for the segmentation.

I am not sure why i modified the NRF_SDH_BLE_GATT_MAX_MTU_SIZE but i changed it to 2003. and the value of NRF_SDH_BLE_GATTS_ATTR_TAB_SIZE is 1408.
the number of bytes that i want to notify is depends on the frame i am sending so it can be 7 bytes and it can reach 261 bytes but when i change the value of hvx_params.p_len with my length it also sends 501 bytes

I don't think our softdevice support NRF_SDH_BLE_GATT_MAX_MTU_SIZE>247. 

Could you capture a sniffer trace when  you do 501 bytes ? 

I would suggest to stick to the 247 bytes and split your notification if needed. 
Note that longer over air packet has more chance of collision and corruption. 

this an old photo but it is for the same code

Hi Elshat, 
Could you please send the full sniffer trace  ? 

Hi Hung,
the attached file is the full sniffer trace in .txt format if it is not clear please tell me which format do you want
thank you,
